电动马达505被构造成能够根据马达的极性在远侧和近侧方向上轴向驱动可纵向运动的驱动构件540。例如，当马达505在一个旋转方向上被驱动时，可纵向运动的驱动构件540将在远侧方向“DD”上被轴向地驱动。当马达505在相反的旋转方向上被驱动时，可纵向运动驱动构件 540将在近侧方向“PD”上被轴向地驱动。柄部组件500可包括开关513，开关513可被构造成能够使通过功率源522施加到电动马达505的极性反转或以其他方式控制马达505。柄部组件500还可包括一个或多个传感器(未示出)，其被构造成能够检测驱动构件540的位置和/或驱动构件 540运动的方向。通过被可枢转地支撑在柄部组件500上的击发触发器 532可控制马达505的致动。击发触发器532可在未致动位置和致动位置之间枢转。击发触发器532可被弹簧(未示出)或其他偏置构造偏置到未致动位置，使得当临床医生释放击发触发器532时，其可被弹簧或偏置构造枢转到或以其他方式返回到未致动位置。在至少一种形式中，击发触发器532可如上所述被定位在闭合触发器512的“外侧”。如美国专利申请公布2015/0272575中所讨论的，柄部组件500可配备有击发触发器安全按钮(未示出)，以防止击发触发器532的无意致动。当闭合触发器512处于未致动位置时，安全按钮被容纳在柄部组件500中，在此情况下，临床医生不能容易地接近安全按钮并使安全按钮在防止击发触发器532的致动的安全位置和其中可击发击发触发器532的击发位置之间运动。在临床医生压下闭合触发器512时，安全按钮和击发触发器 532可向下枢转，然后他们可被临床医生操纵。Theelectric motor 505 is configured to axially drive the longitudinallymovable drive member 540 in distal and proximal directions depending on the polarity of the motor. For example, when themotor 505 is driven in one rotational direction, the longitudinallymovable drive member 540 will be driven axially in the distal direction "DD". When themotor 505 is driven in the opposite rotational direction, the longitudinallymovable drive member 540 will be driven axially in the proximal direction "PD". Thehandle assembly 500 may include aswitch 513 that may be configured to reverse the polarity applied to theelectric motor 505 by thepower source 522 or otherwise control themotor 505 . Thehandle assembly 500 may also include one or more sensors (not shown) configured to detect the position of thedrive member 540 and/or the direction of movement of thedrive member 540. Actuation of themotor 505 may be controlled by a firingtrigger 532 pivotally supported on thehandle assembly 500. The firingtrigger 532 is pivotable between an unactuated position and an actuated position. The firingtrigger 532 may be biased to an unactuated position by a spring (not shown) or other biasing configuration, such that when the clinician releases the firingtrigger 532, it may be pivoted by the spring or biasing configuration or otherwise. way back to the unactuated position. In at least one form, the firingtrigger 532 may be positioned "outside" theclosure trigger 512 as described above. As discussed in US Patent Application Publication 2015/0272575, thehandle assembly 500 may be equipped with a firing trigger safety button (not shown) to prevent inadvertent actuation of the firingtrigger 532 . When theclosure trigger 512 is in the unactuated position, the safety button is housed in thehandle assembly 500, in which case the clinician cannot easily access the safety button and keep the safety button in a position that prevents actuation of the firingtrigger 532. Movement between a safety position and a firing position in which thefiring trigger 532 can be fired. When the clinician depresses theclosure trigger 512, the safety button and firingtrigger 532 can pivot downward, and they can then be manipulated by the clinician.

在至少一种形式中，可纵向运动的驱动构件540可具有形成在其上的齿条齿(未示出)，用于与对应的驱动齿轮装置(未示出)啮合接合，该驱动齿轮装置与马达505连接。关于那些特征的进一步的细节可见于美国专利申请公布2015/0272575。至少一种形式还包括可手动致动的“救助”组件，所述组件能够允许临床医生在马达505变得停用的情况下手动地回缩可纵向运动的驱动构件540。救助组件可包括杠杆或救助柄部组件，其在可释放门550下方储存在柄部组件500内。杠杆被构造成能够被手动枢转成与驱动构件540中的齿棘轮接合。因此，临床医生可通过使用救助柄部组件手动地回缩驱动构件540，以使驱动构件540在近侧方向“PD”上做棘轮运动。名称为“POWERED SURGICAL CUTTING AND STAPLINGAPPARATUS WITH MANUALLY RETRACTABLE FIRING SYSTEM”的美国专利申请序列号12/249,117，现为美国专利申请公布 2010/0089970(其全部公开内容据此以引用方式并入本文)公开了也可与本文公开的工具组件1000一起使用的救助装置和其他部件、装置和系统。In at least one form, the longitudinallymovable drive member 540 may have rack teeth (not shown) formed thereon for meshing engagement with a corresponding drive gear arrangement (not shown) that Connected to themotor 505. Further details on those features can be found in US Patent Application Publication 2015/0272575. At least one form also includes a manually actuatable "rescue" assembly that can allow the clinician to manually retract the longitudinallymovable drive member 540 if themotor 505 becomes deactivated. The rescue assembly may include a lever or rescue handle assembly that is stored withinhandle assembly 500 underreleasable door 550 . The lever is configured to be manually pivotable into ratchet engagement with teeth in thedrive member 540 . Thus, the clinician can manually retract thedrive member 540 using the rescue handle assembly to ratchet thedrive member 540 in the proximal direction "PD".

击发构件1760被构造成能够与滑动组件1120可操作地接合，滑动组件1120被可操作地支撑在外科钉仓1110的主体1111内。滑动组件1120 在外科钉仓体1111内从邻近仓体1111的近侧端部1112的近侧端部起始位置可滑动地移位到邻近仓体1111的远侧端部1113的结束位置。参见图4。仓体1111将多个钉驱动器1170(图81-83)可操作地支撑在其中，这些钉驱动器在中心设置的狭槽1114的每个侧面上成排对准。居中设置的狭槽1114使击发构件1760能够穿过其中并切割夹紧在砧座1130和钉仓1110之间的组织。驱动器与穿过仓体1111的上部平台表面1115打开的对应凹坑或腔1116相关联。钉驱动器中的每一个在其上支撑一个或多个外科钉或紧固件。滑动组件1120包括多个倾斜的或楔形凸轮1122，其中每个凸轮1122对应于位于狭槽1114的侧面上的紧固件或驱动器的特定线。当击发构件1760被击发或朝远侧驱动时，击发构件1760也朝远侧驱动滑动组件1120。当击发构件1760朝远侧运动通过钉仓1110时，组织切割特征部1766切割夹紧在砧座组件1130和钉仓1110之间的组织，并且滑动组件1120在仓中向上驱动驱动器，这驱动对应的钉或紧固件与砧座组件1130成形接触。The firingmember 1760 is configured to be operably engaged with theslide assembly 1120 , which is operably supported within thebody 1111 of thesurgical staple cartridge 1110 .Slide assembly 1120 is slidably displaceable within surgicalstaple cartridge body 1111 from a proximal end starting position adjacentproximal end 1112 ofcartridge body 1111 to an ending position adjacentdistal end 1113 ofcartridge body 1111 . See Figure 4. Thecartridge body 1111 operably supports therein a plurality of staple drivers 1170 (FIGS. 81-83) aligned in rows on each side of a centrally disposedslot 1114. The centrally positionedslot 1114 enables the firingmember 1760 to pass therethrough and cut tissue clamped between theanvil 1130 and thestaple cartridge 1110. The drivers are associated with corresponding pockets orcavities 1116 that open through the upper platform surface 1115 of thecartridge body 1111 . Each of the staple drivers supports one or more surgical staples or fasteners thereon.Slide assembly 1120 includes a plurality of angled or wedge-shapedcams 1122 , where eachcam 1122 corresponds to a particular line of fasteners or drivers located on the sides ofslot 1114 . When the firingmember 1760 is fired or driven distally, the firingmember 1760 also drives theslide assembly 1120 distally. As the firingmember 1760 moves distally through thestaple cartridge 1110, the tissue cutting features 1766 cut tissue clamped between theanvil assembly 1130 and thestaple cartridge 1110, and theslide assembly 1120 drives the driver up in the cartridge, which drives the corresponding The staples or fasteners are in forming contact with theanvil assembly 1130.

在示出的示例中，仓体1111将多个钉驱动器可操作地支撑在其中，这些钉驱动器在居中设置的狭槽1114的每个侧面上成排对准。图81-83 示出了可用于将钉支撑在外科钉仓的一个侧面上的钉驱动器1170的一个示例。位于居中设置的狭槽1114的相对侧上的驱动器可包括驱动器 1170的镜像。也可有效地采用其他钉驱动器构造。如在图81-83中可看到的，钉驱动器1700的一种形式包括钉驱动器主体1172。驱动器主体 1172包括被构造成能够在其上支撑钉(未示出)的第一或最内部钉支撑部分1174。第二或中心钉支撑部分1176被构造成能够在其上支撑另一个钉(未示出)并且第三支撑部分1870被构造成能够在其上支撑第三钉(未示出)。第一钉支撑部分1174、第二钉支撑部分1176和第三钉支撑部分 1178都通过连接器部分1180联接在一起。在至少一种布置中，连接器部分1180形成为具有居中设置的开口或开孔1182，该开口或开孔被构造成能够可滑动地接收形成在仓体中的对应的第一驱动器引导件(未示出)。连接器部分1180包括第一凸轮部分1184，该第一凸轮部分具有形成于其上的第一凸轮表面或斜坡1186。连接器部分1180还包括第二凸轮部分 1188，该第二凸轮部分具有形成于其上的第二凸轮表面1190。凸轮表面 1186、1190具有相同的斜率或角度或它们可具有不同的斜率/角度。在至少一个实施方案中，每个钉驱动器1170都由例如

一体地形成或模制而成，而无填充物。然而，也可使用其它材料，诸如，例如具有玻璃或矿物填充物的

或者尼龙或具有玻璃锉的尼龙。在其它布置中，钉驱动器1170的各个部分可由其他材料分别制成并通过粘合剂、焊料等附接在一起。关于钉驱动器1170以及可与本文所公开的各种实施方案有效地一起使用的其他驱动器实施方案的进一步细节可见于2015年9月2 日提交的名称为“SURGICAL STAPLE CONFIGURATIONS WITH CAMMINGSURFACES LOCATED BETWEEN PORTIONS SUPPORTING SURGICAL STAPLES”的美国专利申请序列号14/843,243，其全部公开内容据此以引用方式并入本文。In the example shown, thecartridge body 1111 operably supports therein a plurality of staple drivers aligned in rows on each side of the centrally disposedslot 1114 . 81-83 illustrate one example of astaple driver 1170 that may be used to support the staples on one side of a surgical staple cartridge. The drives on opposite sides of the centrally positionedslot 1114 may include mirror images of thedrives 1170 . Other staple driver configurations can also be used effectively. As can be seen in FIGS. 81-83 , one form of staple driver 1700 includes astaple driver body 1172 . Thedriver body 1172 includes a first or innermoststaple support portion 1174 configured to support staples (not shown) thereon. The second or centralstaple support portion 1176 is configured to support another staple (not shown) thereon and the third support portion 1870 is configured to support a third staple (not shown) thereon. The firststaple support portion 1174 , the secondstaple support portion 1176 , and the thirdstaple support portion 1178 are all coupled together by aconnector portion 1180 . In at least one arrangement, theconnector portion 1180 is formed with a centrally disposed opening oraperture 1182 configured to slidably receive a corresponding first driver guide ( not shown).

Further details regarding thestaple driver 1170 and other driver implementations that may be used effectively with the various embodiments disclosed herein can be found in a filing on September 2, 2015 entitled "SURGICAL STAPLE CONFIGURATIONS WITH CAMMINGSURFACES LOCATED BETWEEN PORTIONS SUPPORTING SURGICAL STAPLES" US Patent Application Serial No. 14/843,243, the entire disclosure of which is hereby incorporated by reference herein.

钉腔1116相对于轴轴线SA成角度地取向。更具体地，钉腔1116相对于轴轴线SA以斜角取向，并且在平台表面1115中形成人字形图案。本文描述了钉仓体中的钉腔的各种另选的图案。Thestaple cavity 1116 is oriented at an angle relative to the shaft axis SA. More specifically, thestaple cavities 1116 are oriented at an oblique angle relative to the shaft axis SA and form a herringbone pattern in the platform surface 1115 . Various alternative patterns of staple cavities in staple cartridge bodies are described herein.

钉线中的钉的布置和/或几何结构的变化可影响钉线的柔性和密封特性。例如，由线性钉构成的钉线可提供有限量的柔性或拉伸，因为钉线可在线性钉之间挠曲或拉伸。因此，钉线的有限部分(例如，钉之间的部分)是柔性的。由成角度地取向的钉构成的钉线也可在钉之间挠曲或拉伸。然而，成角度取向的钉也能够旋转，这在钉线内提供附加的拉伸程度。例如，由成角度地取向的钉构成的钉线可拉伸超过60％。在某些实例中，例如，由成角度取向的钉构成的钉线可拉伸至少25％或至少 50％。例如，钉的布置包括钉的相对取向和钉之间的间距。例如，钉的几何结构包括钉的尺寸和形状。基于钉的布置和/或几何结构，钉线的柔性和密封特性可在纵向和/或侧向位置处改变。在某些实例中，希望在沿钉线的一个或多个位置处改变钉线的柔性和/或密封特性。例如，可希望使钉线或其一部分的柔性最大化。除此之外或另选地，可希望使钉线或其一部分的柔性最小化。也可希望使钉线或其一部分的密封特性最大化。除此之外或另选地，可希望使钉线或其一部分的密封特性最小化。Variations in the arrangement and/or geometry of the staples in the staple line can affect the flexibility and sealing properties of the staple line. For example, a staple line composed of linear staples can provide a limited amount of flexibility or stretch, as the staple line can flex or stretch between the linear staples. Thus, a limited portion of the staple line (eg, the portion between the staples) is flexible. Staple lines composed of angularly oriented staples can also flex or stretch between the staples. However, angularly oriented staples can also be rotated, which provides an additional degree of stretch within the staple line. For example, staple lines composed of angularly oriented staples can stretch by more than 60%. In certain instances, for example, a staple line comprised of angularly oriented staples can stretch by at least 25% or at least 50%. For example, the arrangement of the staples includes the relative orientation of the staples and the spacing between the staples. For example, the geometry of the staple includes the size and shape of the staple. Based on the arrangement and/or geometry of the staples, the flexibility and sealing properties of the staple line may vary at longitudinal and/or lateral locations. In certain instances, it may be desirable to vary the flexibility and/or sealing properties of the staple line at one or more locations along the staple line. For example, it may be desirable to maximize the flexibility of the staple line or a portion thereof. Additionally or alternatively, it may be desirable to minimize the flexibility of the staple line or a portion thereof. It may also be desirable to maximize the sealing properties of the staple line or a portion thereof. Additionally or alternatively, it may be desirable to minimize the sealing properties of the staple line or a portion thereof.

钉仓中钉腔的布置对应于钉仓所产生的钉线中的钉的布置。例如，钉仓中的钉腔的间距和相对取向对应于由钉仓产生的钉线中的钉的间距和相对取向。在各种实例中，钉仓可包括钉腔的布置，其被选择和/或设计成优化所得钉线的柔性和/或密封特性。例如，外科医生可基于待执行的外科手术和/或外科手术期间待治疗的组织的特性来选择具有特定布置的钉腔的钉仓。The arrangement of the staple cavities in the staple cartridge corresponds to the arrangement of the staples in the staple line produced by the staple cartridge. For example, the spacing and relative orientation of the staple cavities in the staple cartridge correspond to the spacing and relative orientation of the staples in the staple line produced by the staple cartridge. In various examples, a staple cartridge can include an arrangement of staple cavities selected and/or designed to optimize the flexibility and/or sealing properties of the resulting staple wire. For example, a surgeon may select a staple cartridge with a specific arrangement of staple cavities based on the surgical procedure to be performed and/or the characteristics of the tissue to be treated during the surgical procedure.

在某些实例中，可希望产生具有不同钉图案的钉线。钉线可包括用于其第一部分的第一钉图案和用于其第二部分的第二钉图案。第一图案和第二图案可纵向偏置。例如，第一图案可被定位在钉线的近侧端部或远侧端部处。在其他实例中，第一图案和第二图案可侧向偏置，并且在其他实例中，第一图案和第二图案可侧向偏置和纵向偏置。钉线可包括至少两种不同的钉图案。In certain instances, it may be desirable to produce staple lines with different staple patterns. The staple line may include a first staple pattern for its first portion and a second staple pattern for its second portion. The first pattern and the second pattern may be longitudinally offset. For example, the first pattern can be positioned at the proximal end or the distal end of the staple line. In other examples, the first pattern and the second pattern can be offset laterally, and in other examples, the first pattern and the second pattern can be offset laterally and longitudinally. The staple line can include at least two different staple patterns.

在某些实例中，钉线中的大部分钉可形成主图案，并且钉线中的其他钉可形成一个或多个次图案。主图案可跨越钉线的重要部分并且可包括纵向重复的子图案。在某些实例中，次图案或不规则形状可偏离主图案。次图案可以是例如沿钉线的长度的一个或多个位置处的异常。钉线中的不同图案可被构造成能够在预定位置处产生不同的特性。例如，主图案可为高度柔性或弹性的图案，其可允许缝合的组织的广泛拉伸，并且次图案可较不柔性或较不弹性。例如，可希望大部分钉线高度柔性，并且一个或多个有限部分柔性较低。在其他实例中，次图案可比主图案更具柔性。在某些实例中，由于次图案沿钉线的较短部分延伸，因此次图案的柔性可不影响或不会显著影响整个钉线的总体柔性。In some instances, a majority of the staples in the staple line can form a primary pattern, and other staples in the staple line can form one or more secondary patterns. The main pattern can span a significant portion of the staple line and can include longitudinally repeating sub-patterns. In some instances, the secondary pattern or irregular shape may deviate from the primary pattern. The secondary pattern may be, for example, anomalies at one or more locations along the length of the staple line. Different patterns in the staple line can be configured to produce different properties at predetermined locations. For example, the primary pattern may be a highly flexible or elastic pattern that may allow extensive stretching of the stapled tissue, and the secondary pattern may be less flexible or less elastic. For example, it may be desirable for most of the staple line to be highly flexible, and one or more limited portions to be less flexible. In other examples, the secondary pattern may be more flexible than the primary pattern. In some instances, since the sub-pattern extends along a shorter portion of the staple line, the flexibility of the sub-pattern may not affect or significantly affect the overall flexibility of the entire staple line.

现在参见图5-8，示出了与外科端部执行器一起使用的钉仓体3000。钉仓体3000包括平台3002和狭槽3004，该狭槽从近侧端部3006朝向仓体3000的远侧端部3008延伸穿过平台3002。狭槽3004沿仓体3000的纵向轴线LA(图7)延伸。钉腔3010限定在仓体3000中，并且每个钉腔 3010在平台3002中限定开口3012。Referring now to Figures 5-8, astaple cartridge body 3000 is shown for use with a surgical end effector. Thecartridge body 3000 includes aplatform 3002 and aslot 3004 extending through theplatform 3002 from theproximal end 3006 toward thedistal end 3008 of thecartridge body 3000 . Theslot 3004 extends along the longitudinal axis LA of the cartridge body 3000 (FIG. 7).Staple cavities 3010 are defined in thecartridge body 3000, and eachstaple cavity 3010 defines anopening 3012 in theplatform 3002.

大多数钉腔3010被布置成第一图案或主图案3020。第一图案3020 为成角度取向的钉腔3010的纵向重复的图案。纵向重复的图案是其中子图案或布置纵向重复的图案。例如，狭槽3004的每个侧面上的三个钉腔 (内部钉腔、中间钉腔和外部钉腔)的布置可沿钉仓体3000的长度的至少一部分重复。成角度取向的钉腔的各种纵向重复的图案描述于2014年9月26日提交的名称为“METHOD FOR CREATING A FLEXIBLE STAPLE LINE”的美国专利申请号14/498,145，现为美国专利申请公布 2016/0089142，该专利申请全文以引用方式并入本文。第一图案3020中的钉腔3010的开口3012形成人字形图案，其在仓平台3002中具有六排成角度取向的钉腔开口3012。钉腔3010的内排3014a、中间排3014b和外排3014c被定位在狭槽3004的每个侧面上。Most of thestaple cavities 3010 are arranged in a first pattern ormain pattern 3020 . Thefirst pattern 3020 is a longitudinally repeating pattern of angularly orientedstaple cavities 3010 . A longitudinally repeated pattern is a pattern in which sub-patterns or arrangements are longitudinally repeated. For example, the arrangement of three staple cavities (inner staple cavities, middle staple cavities, and outer staple cavities) on each side ofslot 3004 may be repeated along at least a portion of the length ofstaple cartridge body 3000. Various longitudinally repeating patterns of angularly oriented staple cavities are described in US Patent Application No. 14/498,145, "METHOD FOR CREATING A FLEXIBLE STAPLE LINE," filed September 26, 2014, now US Patent Application Publication 2016 /0089142, which is incorporated herein by reference in its entirety. Theopenings 3012 of thestaple cavities 3010 in thefirst pattern 3020 form a herringbone pattern with six rows of angularly orientedstaple cavity openings 3012 in thecartridge deck 3002 . Aninner row 3014a , amiddle row 3014b , and anouter row 3014c ofstaple cavities 3010 are positioned on each side of theslot 3004 .

每个钉腔开口3012具有近侧端部3016和远侧端部3018。第一图案 3020中的钉腔3010的近侧端部3016和远侧端部3018侧向偏置。换句话说，第一图案3020中的每个钉腔3010相对于纵向轴线LA(图7)成角度地取向。腔轴线CA(图7)在每个开口3012的近侧端部3016和远侧端部3018之间延伸。腔轴线CA相对于狭槽3004倾斜地取向。更具体地，钉腔3010的内排3014a和钉腔3010的外排3014c中的开口3012以相对于纵向轴线LA的45度或约45度取向，并且钉腔3010的中间排3014b中的开口3012以相对于内排3014a和外排3014a的开口3012的90度或约 90度取向。Eachstaple cavity opening 3012 has aproximal end 3016 and adistal end 3018. Theproximal end 3016 and thedistal end 3018 of thestaple cavity 3010 in thefirst pattern 3020 are laterally offset. In other words, eachstaple cavity 3010 in thefirst pattern 3020 is oriented at an angle relative to the longitudinal axis LA (FIG. 7). The lumen axis CA ( FIG. 7 ) extends between theproximal end 3016 and thedistal end 3018 of eachopening 3012 . The cavity axis CA is oriented obliquely with respect to theslot 3004 . More specifically, theopenings 3012 in theinner row 3014a ofstaple cavities 3010 and theouter row 3014c ofstaple cavities 3010 are oriented at or about 45 degrees relative to the longitudinal axis LA, and theopenings 3012 in themiddle row 3014b ofstaple cavities 3010 Oriented at or about 90 degrees relative to theopenings 3012 of the inner andouter rows 3014a and 3014a.

仓体3000中的某些钉腔3010以相对于第一图案3020中的钉腔3010 异常或不规则的角度取向。更具体地，近侧钉腔3010a，3010b，3010c和 3010d以及远侧钉腔3010e，3010f，3010g和3010h的角度取向不符合第一图案3020中的钉腔3010的人字形布置。相反，近侧钉腔3010a-3010d和远侧钉腔3010e-3010h与第一图案3020中的钉腔3010成角度地偏置。近侧钉腔3010a，3010b，3010c和3010d相对于第一图案3020中的钉腔3010 倾斜地取向，并且远侧钉腔3010e，3010f，3010g和3010h也相对于第一图案3020中的钉腔3010倾斜地取向。近侧钉腔和远侧钉腔3010a-3010h 被取向成平行于狭槽3004并且平行于纵向轴线LA。Some of thestaple cavities 3010 in thecartridge body 3000 are oriented at abnormal or irregular angles relative to thestaple cavities 3010 in thefirst pattern 3020. More specifically, the angular orientation of theproximal staple cavities 3010a, 3010b, 3010c and 3010d and thedistal staple cavities 3010e, 3010f, 3010g and 3010h do not conform to the herringbone arrangement of thestaple cavities 3010 in thefirst pattern 3020. In contrast,proximal staple cavities 3010a-3010d anddistal staple cavities 3010e-3010h are angularly offset fromstaple cavities 3010 infirst pattern 3020.Proximal staple cavities 3010a, 3010b, 3010c, and 3010d are oriented obliquely relative tostaple cavities 3010 infirst pattern 3020, anddistal staple cavities 3010e, 3010f, 3010g, and 3010h are also oriented relative tostaple cavities 3010 infirst pattern 3020 oriented obliquely. The proximal anddistal staple cavities 3010a-3010h are oriented parallel to theslot 3004 and parallel to the longitudinal axis LA.

近侧钉腔3010a-3010d形成与第一图案3020不同的近侧图案3022，并且远侧钉腔3010e-3010h形成也与第一图案3020不同的远侧图案3024。在所示出的布置中，近侧图案3022包括在狭槽3004的第一侧上的第一对平行的、纵向对准的钉腔3010a，3010b以及在纵向狭槽3004的第二侧上的第二对平行的、纵向对准的钉腔3010c，3010d。远侧图案3024还包括在纵向狭槽3004的第一侧上的第一对平行的、纵向对准的钉腔3010e， 3010f以及在纵向狭槽3004的第二侧上的第二对平行的、纵向对准的钉腔3010g，3010h。在其他实例中，远侧图案3024可与近侧图案3022不同。Theproximal staple cavities 3010a-3010d form a differentproximal pattern 3022 than thefirst pattern 3020, and thedistal staple cavities 3010e-3010h form adistal pattern 3024 that is also different from thefirst pattern 3020. In the arrangement shown,proximal pattern 3022 includes a first pair of parallel, longitudinally alignedstaple cavities 3010a, 3010b on a first side ofslot 3004 and a A second pair of parallel, longitudinally alignedstaple cavities 3010c, 3010d.Distal pattern 3024 also includes a first pair of parallel, longitudinally alignedstaple cavities 3010e, 3010f on a first side oflongitudinal slot 3004 and a second pair of parallel, longitudinally alignedstaple cavities 3010f on a second side oflongitudinal slot 3004 Longitudinal alignedstaple cavities 3010g, 3010h. In other examples, thedistal pattern 3024 can be different from theproximal pattern 3022.

近侧图案3022和远侧图案3024相对于纵向轴线LA对称。在其他实例中，近侧图案3022和/或远侧图案3024可相对于纵向轴线LA不对称。例如，钉腔3010e和3010f可与钉腔3010g和3010h纵向偏置和/或钉腔 3010a和3010b可与钉腔3010c和3010d纵向偏置。除此之外或另选地，在某些实例中，钉仓体3000可包括近侧图案3022或远侧图案3024。在其他实例中，限定在钉仓体3000中的钉腔3010可包括钉腔3010的附加的和/或不同的图案。Theproximal pattern 3022 and thedistal pattern 3024 are symmetrical with respect to the longitudinal axis LA. In other examples,proximal pattern 3022 and/ordistal pattern 3024 may be asymmetrical relative to longitudinal axis LA. For example,staple cavities 3010e and 3010f can be longitudinally offset fromstaple cavities 3010g and 3010h and/orstaple cavities 3010a and 3010b can be longitudinally offset fromstaple cavities 3010c and 3010d. Additionally or alternatively, in some examples, thestaple cartridge body 3000 can include aproximal pattern 3022 or adistal pattern 3024. In other examples, thestaple cavities 3010 defined in thestaple cartridge body 3000 may include additional and/or different patterns ofstaple cavities 3010 .

主要参见图5，无创伤扩张器3030围绕第一图案3020中的钉腔3010 的一部分从平台3002延伸或突出。无创伤扩张器3030分别围绕第一图案3020中的钉腔3010的开口3012的近侧端部3016和远侧端部3018。无创伤扩张器3030可被构造成能够抓持由端部执行器夹紧的组织。除此之外或另选地，在某些实例中，钉腿的尖端可从仓体3000突出。在所述实例中，无创伤扩张器3030可被构造成能够与钉腿的尖端齐平地延伸和/ 或延伸超出钉腿的尖端，以防止尖端过早地穿透组织。因此，较大的钉 (例如具有较长腿的钉)可被定位在钉腔3010中，钉腔3010具有被定位在其周围的无创伤扩张器3030。例如，再次参见图5，较大的钉可被定位在第一图案3020中的钉腔3010中，而不是近侧图案3022和远侧图案3024中的钉腔中的钉，同时不存在由较长的钉腿过早刺穿组织的风险。在某些实例中，无创伤扩张器3030可被定位在近侧图案3022和/或远侧图案3024中的钉腔3010周围，并且较大的钉也可被定位在那些钉腔3010a-3010h中的一个或多个中。Referring primarily to FIG. 5 , theatraumatic dilator 3030 extends or protrudes from theplatform 3002 around a portion of thestaple cavity 3010 in thefirst pattern 3020 . Theatraumatic dilator 3030 surrounds theproximal end 3016 and thedistal end 3018 of theopening 3012 of thestaple cavity 3010 in thefirst pattern 3020, respectively. Theatraumatic dilator 3030 can be configured to grasp tissue clamped by the end effector. Additionally or alternatively, the tips of the staple legs can protrude from thecartridge body 3000 in some instances. In the example, theatraumatic dilator 3030 may be configured to extend flush with and/or beyond the tips of the staple legs to prevent premature penetration of the tissue by the tips. Thus, larger staples (eg, staples with longer legs) can be positioned in thestaple cavity 3010 with theatraumatic dilator 3030 positioned therearound. For example, referring again to FIG. 5, larger staples may be positioned instaple cavities 3010 infirst pattern 3020 rather than staple cavities inproximal pattern 3022 anddistal pattern 3024, without the presence of larger staples Risk of premature piercing of tissue by long spike legs. In certain instances,atraumatic dilators 3030 can be positioned aroundstaple cavities 3010 inproximal pattern 3022 and/ordistal pattern 3024, and larger staples can also be positioned in thosestaple cavities 3010a-3010h one or more of.

钉仓体3000可被构造成能够产生沿其长度具有不同特性的钉线。由钉仓体3000产生并嵌入组织T中的钉线3040在图9中示出。钉线3040 由钉3042构成，并且用于与本文所述的各种钉仓一起使用的示例性钉 3042在图10中示出。例如，钉3042可由弯曲的线材构成。线材的直径可具有0.0079英寸或约0.0079英寸的直径。在其他实例中，线材可具有 0.0089英寸或约0.0089英寸的直径。在其他实例中，线材可具有0.0094 英寸或约0.0094英寸的直径。在某些实例中，线材可具有小于0.0079英寸或大于0.0094英寸的直径。读者将理解，线材的直径可决定钉的直径。钉3042是大致U形的钉，其具有基部3050，从基部3050的第一端部延伸的第一腿部3052，以及从基部3050的第二端部延伸的第二腿部3054。第一腿部3052基本上平行于第二腿部3054并且基本上垂直于基部3050。当植入组织T中时，基部3050的角度取向对应于钉3042从其被击发的钉腔开口3012的角度取向。Thestaple cartridge body 3000 can be configured to produce staple wires with different properties along its length. Thestaple wires 3040 produced by thestaple cartridge body 3000 and embedded in the tissue T are shown in FIG. 9 . Thestaple line 3040 is comprised ofstaples 3042, andexemplary staples 3042 for use with the various staple cartridges described herein are shown in FIG. 10 . For example, thestaples 3042 may be constructed of curved wire. The diameter of the wire may have a diameter of 0.0079 inches or about 0.0079 inches. In other examples, the wire may have a diameter of 0.0089 inches or about 0.0089 inches. In other examples, the wire may have a diameter of 0.0094 inches or about 0.0094 inches. In certain examples, the wire may have a diameter of less than 0.0079 inches or greater than 0.0094 inches. The reader will understand that the diameter of the wire may determine the diameter of the staple. Thestaple 3042 is a generally U-shaped staple having abase 3050 , afirst leg 3052 extending from a first end of thebase 3050 , and asecond leg 3054 extending from a second end of thebase 3050 . Thefirst leg 3052 is substantially parallel to thesecond leg 3054 and substantially perpendicular to thebase 3050 . When implanted in tissue T, the angular orientation of thebases 3050 corresponds to the angular orientation of thestaples 3042 from thestaple cavity openings 3012 from which they are fired.

用于与本文所述的各种钉仓一起使用的另一个示例性钉3142在图 11中示出。钉3142是大致V形的钉，其具有基部3150，从基部3050的第一端部延伸的第一腿部3152，以及从基部3150的第二端部延伸的第二腿部3154。第一腿部3152相对于第二腿部3154和基部3150倾斜地取向。当植入组织T中时，基部3150的取向对应于钉3142从其被击发的钉腔开口3012的取向。读者将理解，具有不同几何结构的钉也可从本文所述的钉仓被击发。Anotherexemplary staple 3142 for use with the various staple cartridges described herein is shown in FIG. 11 . Thestaple 3142 is a generally V-shaped staple having abase 3150 , afirst leg 3152 extending from a first end of thebase 3050 , and asecond leg 3154 extending from a second end of thebase 3150 . Thefirst leg 3152 is oriented obliquely with respect to thesecond leg 3154 and thebase 3150 . When implanted in tissue T, the orientation of thebase 3150 corresponds to the orientation of thestaple cavity opening 3012 from which thestaples 3142 are fired. The reader will understand that staples with different geometries can also be fired from the staple cartridges described herein.

再次参见图9，钉线3040包括第一部分3044、近侧部分3046和远侧部分3048。第一部分3044由第一图案或主图案3020产生并且沿钉线3040 的大部分延伸。由于钉3042在第一部分3044中的角度取向，第一部分 3044是基本上柔性的或柔顺的。例如，因为在使对组织T的创伤最小化的同时成角度取向的钉3042可在缝合组织T内旋转，所以第一部分3044被构造成能够在缝合组织拉伸时纵向和/或侧向拉伸或延伸。Referring again to FIG. 9 , thestaple line 3040 includes afirst portion 3044 , aproximal portion 3046 and adistal portion 3048 . Thefirst portion 3044 is created by the first pattern ormain pattern 3020 and extends along most of thestaple line 3040 . Due to the angular orientation of thestaples 3042 in thefirst portion 3044, thefirst portion 3044 is substantially flexible or compliant. For example, because the angularly orientedstaples 3042 can be rotated within the stapled tissue T while minimizing trauma to the tissue T, thefirst portion 3044 is configured to stretch longitudinally and/or laterally as the stapled tissue is stretched or extension.

近侧部分3046从近侧图案3022产生并且形成钉线3040的近侧端部。远侧部分3048由远侧图案3024产生并且形成钉3040的远侧端部。由于钉3042在钉线3040的近侧部分3046和远侧部分3048中的平行取向，钉线3040的近侧部分3046和远侧部分3046可具有比第一部分3044更小的柔性。然而，近侧部分3046和远侧部分3048的柔性降低可不会影响或基本上不影响钉线3040的整体柔性。此外，如本文所述，近侧部分3046 和远侧部分3048可不邻近切割线延伸，并且在某些实例中，近侧部分 3046可不存在或从钉线3040中缺失。Aproximal portion 3046 is created from theproximal pattern 3022 and forms the proximal end of thestaple line 3040. Thedistal portion 3048 is created from thedistal pattern 3024 and forms the distal end of thestaple 3040. Theproximal portion 3046 and thedistal portion 3046 of thestaple line 3040 may have less flexibility than thefirst portion 3044 due to the parallel orientation of thestaples 3042 in theproximal portion 3046 and thedistal portion 3048 of thestaple line 3040 . However, the reduced flexibility ofproximal portion 3046 anddistal portion 3048 may not affect or substantially affect the overall flexibility ofstaple wire 3040. Furthermore, as described herein,proximal portion 3046 anddistal portion 3048 may not extend adjacent the cutting line, and in certain instances,proximal portion 3046 may be absent or absent fromstaple line 3040.

击发元件诸如击发构件1760(图4)被构造成能够沿狭槽3004的至少一部分运动，以从钉腔3010击发钉3042。击发元件可包括和/或接合一个或多个楔形滑动件和/或凸轮表面，诸如具有楔形凸轮1122(图4) 的滑动组件1120。例如，滑动件的凸轮被构造成能够朝向钉成形表面向上驱动钉，诸如在砧座1130(图1、图3和图4)中形成凹坑。参见图6，钉仓体3000包括沿底表面3034的多个通道3036，楔形凸轮在击发行程期间可运动通过通道3036。A firing element such as firing member 1760 ( FIG. 4 ) is configured to be movable along at least a portion ofslot 3004 to firestaples 3042 fromstaple cavity 3010 . The firing element may include and/or engage one or more wedge-shaped slides and/or cam surfaces, such asslide assembly 1120 with wedge-shaped cam 1122 (FIG. 4). For example, the cam of the slider is configured to drive the staples upwardly toward the staple forming surface, such as to form pockets in the anvil 1130 (FIGS. 1, 3, and 4). Referring to Figure 6, thestaple cartridge body 3000 includes a plurality ofchannels 3036 along thebottom surface 3034 through which the wedge-shaped cam can move during the firing stroke.

在使用中，靶组织夹紧在钉仓体3000和砧座诸如砧座1130(图1、图3和图4)之间。与钉腔3010重叠的组织被缝合。如果组织未被定位在某些钉腔3010上，则从那些钉腔3010击发的钉可不接合组织。砧座通常包括通常称为“组织止挡件”的向下延伸的侧壁。组织止挡件被构造成能够阻止靶组织在砧座和钉仓之间变得过近。例如，参见图4中的端部执行器1100，砧座1130包括组织止挡件1131，其朝向钉仓1110延伸。当砧座1130朝向仓1110闭合时，砧座1130的任一侧上的组织止挡件1131向下延伸经过仓平台表面1115并且形成壁或屏障，这防止组织在砧座1130和仓1110之间定位得过近。组织止挡件1131的远侧端部限定了切割线的近侧起始点。对应于组织止挡件1131的远侧端部的近侧轴线PA在图7中示出。因为靶组织未被定位在近侧轴线PA的近侧，所以从位于近侧轴线PA近侧的钉腔(即，近侧钉腔3010a-3010d)击发的钉不会被击发到靶组织中。在所述实例中，从近侧图案3022击发的钉未形成钉线的一部分。In use, the target tissue is clamped betweencartridge body 3000 and an anvil, such as anvil 1130 (FIGS. 1, 3, and 4). The tissue overlapping thestaple cavity 3010 is stapled. If tissue is not positioned oncertain staple cavities 3010, staples fired from thosestaple cavities 3010 may not engage tissue. Anvils typically include downwardly extending side walls commonly referred to as "tissue stops." The tissue stop is configured to prevent the target tissue from becoming too close between the anvil and the staple cartridge. For example, referring to theend effector 1100 in FIG. 4 , theanvil 1130 includes atissue stop 1131 that extends toward thestaple cartridge 1110 . When theanvil 1130 is closed toward thecartridge 1110 , the tissue stops 1131 on either side of theanvil 1130 extend down past the cartridge deck surface 1115 and form a wall or barrier that prevents tissue from getting between theanvil 1130 and thecartridge 1110 Positioned too close. The distal end of thetissue stop 1131 defines the proximal starting point of the cutting line. The proximal axis PA corresponding to the distal end of thetissue stop 1131 is shown in FIG. 7 . Because the target tissue is not positioned proximal to proximal axis PA, staples fired from staple cavities located proximal to proximal axis PA (ie,proximal staple cavities 3010a-3010d) are not fired into the target tissue. In the example, staples fired fromproximal pattern 3022 do not form part of the staple line.

切割元件3028(图7)还被构造成能够沿纵向狭槽3004运动。在各种实例中，切割元件3028可以是击发元件的整体部分，诸如击发构件 1760(图4)上的组织切割特征部1766。切割元件3028具有远侧切割边缘3029，远侧切割边缘3029被构造成能够切割由端部执行器夹紧并由钉 3042缝合的组织。主要参见图7，切割元件3028的切割边缘3029被构造成能够在仓体3000的近侧端部部分3006附近的近侧位置和仓体3000的远侧端部部分3008附近的远侧位置之间运动。切割边缘3029的最远侧位置由切割线的远侧终止点限定。对应于切割边缘3029的远侧终止点的远侧轴线DA在图7中示出。被定位在远侧轴线DA远侧的组织在击发行程期间未被切割元件3028切开。The cutting element 3028 ( FIG. 7 ) is also configured to be movable along thelongitudinal slot 3004 . In various examples, cuttingelement 3028 may be an integral part of a firing element, such astissue cutting feature 1766 on firing member 1760 (FIG. 4). Cuttingelement 3028 has adistal cutting edge 3029 configured to cut tissue that is gripped by the end effector and stapled bystaples 3042. Referring primarily to FIG. 7 , thecutting edge 3029 of thecutting element 3028 is configured to be positioned between a proximal position near theproximal end portion 3006 of thecartridge body 3000 and a distal position near thedistal end portion 3008 of thecartridge body 3000 sports. The distal-most location of thecutting edge 3029 is defined by the distal termination point of the cutting line. The distal axis DA corresponding to the distal termination point of thecutting edge 3029 is shown in FIG. 7 . Tissue positioned distal to distal axis DA is not cut by cuttingelement 3028 during the firing stroke.

钉腔3010的第一图案3020在近侧轴线PA和远侧轴线DA之间延伸。此外，第一图案3020中的至少一个钉腔3010与近侧轴线PA和远侧轴线 DA重叠。在其他实例中，钉腔3010的多于一个纵向重复的图案可被定位在近侧轴线PA和远侧轴线DA之间。近侧图案3022被定位在近侧轴线PA的近侧，并且远侧图案3024被定位在远侧轴线DA的远侧。在所述实例中，从远侧钉腔3010e-3010h击发的钉不被构造成能够缝合切开的组织。此外，从近侧钉腔3010a-3010d击发的钉不被构造成能够缝合靶组织。因此，这种钉可不会影响所得到的钉线的柔性和/或密封质量。Afirst pattern 3020 ofstaple cavities 3010 extends between the proximal axis PA and the distal axis DA. Additionally, at least onestaple cavity 3010 in thefirst pattern 3020 overlaps the proximal axis PA and the distal axis DA. In other examples, more than one longitudinally repeating pattern ofstaple cavities 3010 may be positioned between the proximal axis PA and the distal axis DA.Proximal pattern 3022 is positioned proximal to proximal axis PA, anddistal pattern 3024 is positioned distal to distal axis DA. In the example, the staples fired from thedistal staple cavities 3010e-3010h are not configured to suturing the incised tissue. Furthermore, the staples fired from theproximal staple cavities 3010a-3010d are not configured to staple the target tissue. Thus, such staples may not affect the flexibility and/or sealing quality of the resulting staple wire.

在某些实例中，可希望产生具有邻近切割线的第一柔性和在切割线近侧和/或远侧的不同柔性的钉线。例如，在切割线的每个侧面上包括至少两个平行钉并且被定位在切割线的远侧端部远侧的钉线可提供某些优点。在某些实例中，提供较小柔性的钉布置可防止和/或限制切割线的传播和/或组织的撕裂。另外，与未切割部分相邻的组织可比与切割线相邻的组织经受更小的应力和/或应变，因此可需要较小的柔性来预防和/或限制组织创伤。更具体地，与切割线相邻的组织可在切割行程期间经受更多的力，并且因此增加的柔性可防止对组织的创伤。另外，与切割线相邻的组织可在其愈合时拉伸，并且因此增加的柔性可促进愈合过程。例如，对于经受较少力的组织，诸如切割线远侧的组织，降低的柔性可增强或加强钉线并防止切割线的远侧传播。In certain instances, it may be desirable to create a staple line with a first flexibility adjacent the cut line and a different flexibility proximal and/or distal to the cut line. For example, a line of staples that includes at least two parallel staples on each side of the cutting line and that is positioned distal to the distal end of the cutting line may provide certain advantages. In certain instances, staple arrangements that provide less flexibility can prevent and/or limit the propagation of cutting lines and/or tearing of tissue. Additionally, tissue adjacent the uncut portion may experience less stress and/or strain than tissue adjacent the cut line, and thus may require less flexibility to prevent and/or limit tissue trauma. More specifically, tissue adjacent the cutting line may experience more force during the cutting stroke, and thus increased flexibility may prevent trauma to the tissue. Additionally, the tissue adjacent to the cut line can stretch as it heals, and thus the increased flexibility can facilitate the healing process. For example, for tissue that experiences less force, such as tissue distal to the cutting line, the reduced flexibility may enhance or strengthen the staple line and prevent distal propagation of the cutting line.

在所示出的布置中，近侧图案3022包括在刀狭槽3004的每个侧面上与第一图案3020的近侧端部相邻的两个不规则的钉腔，并且远侧图案 3024包括在刀狭槽3004的每个侧面上与第一图案3020的远侧端部相邻的两个不规则钉腔。在其他实例中，近侧图案3022和/或远侧图案3024 可由刀狭槽3004的一侧或两侧上的单个不规则钉腔构成。在其他实例中，近侧图案3022和/或远侧图案3024可包括在刀狭槽3004的一侧或两侧上的三个或更多个不规则钉腔。近侧图案3022和/或远侧图案3024可包括纵向重复的子图案。例如，近侧图案3022和/或远侧图案3024可包括多列平行的钉腔开口3012。在某些实例中，钉仓体3000可具有单个不规则图案，其可被定位在第一图案3020的近侧端部或远侧端部处。In the arrangement shown,proximal pattern 3022 includes two irregular staple cavities adjacent the proximal end offirst pattern 3020 on each side ofknife slot 3004, anddistal pattern 3024 includes Two irregular staple cavities adjacent the distal end of thefirst pattern 3020 on each side of theknife slot 3004. In other examples,proximal pattern 3022 and/ordistal pattern 3024 may consist of a single irregular staple cavity on one or both sides ofknife slot 3004 . In other examples,proximal pattern 3022 and/ordistal pattern 3024 may include three or more irregular staple cavities on one or both sides ofknife slot 3004 . Theproximal pattern 3022 and/or thedistal pattern 3024 may include longitudinally repeating sub-patterns. For example, theproximal pattern 3022 and/or thedistal pattern 3024 can include multiple rows of parallelstaple cavity openings 3012 . In certain examples, thestaple cartridge body 3000 can have a single irregular pattern, which can be positioned at the proximal end or the distal end of thefirst pattern 3020.

在某些实例中，近侧图案3022和/或远侧图案3024中的一个或多个钉腔可与刀狭槽3004不平行。例如，这种钉腔可垂直于刀狭槽3004进行取向或相对于刀狭槽3004以倾斜角进行取向。除此之外或另选地，近侧图案3022和/或远侧图案3024中的某些钉腔可彼此不平行。In certain examples, one or more staple cavities inproximal pattern 3022 and/ordistal pattern 3024 may be non-parallel toknife slot 3004. For example, such staple cavities may be oriented perpendicular to theknife slot 3004 or at an oblique angle relative to theknife slot 3004. Additionally or alternatively, some of the staple cavities inproximal pattern 3022 and/ordistal pattern 3024 may be non-parallel to each other.

主要参见图8，钉驱动器3060被定位在仓体3000的钉腔3010中。钉驱动器3060定位成将钉3042支撑在其中(图9和图10)并且在击发行程期间从钉腔3010驱动钉3042。由于仓体3000中的钉腔3010的不同图案，例如图案3020,3022和3024，钉驱动器3060可具有不同的几何结构和/或取向。例如，被定位在第一图案3020的钉腔3010中的钉驱动器 3060可包括连接的驱动器，该连接的驱动器描述于2014年9月26日提交的名称为“METHOD FORCREATING A FLEXIBLE STAPLE LINE”的美国专利申请号14/498,145，现为美国专利申请公布2016/0089142，其全部内容以引用方式并入本文。每个连接的驱动器可包括位于内排3014a 中的钉腔3010中的内部驱动器，位于中间排3014b中的钉腔3010中的中间驱动器，以及位于外排3014c中的钉腔3010中的外部驱动器。连接凸缘可将中间驱动器连接到至少一个内部驱动器和至少一个外部驱动器。在其他实例中，被定位在第一图案3020中的钉腔中的钉驱动器可包括单独的驱动器，其中每个驱动器驱动单个钉。在其他实例中，钉可以是直接驱动钉，其可通过与楔形滑动件和/或凸轮表面的直接接触来驱动，如 2013年12月23日提交的名称为“SURGICAL STAPLES AND STAPLE CARTRIDGES”的美国专利申请号14/138,475(现为美国专利申请公布 2015/0173749)以及美国专利申请号14/498,145中所描述的，它们各自的全部内容以引用方式并入本文。Referring primarily to FIG. 8 ,staple drivers 3060 are positioned instaple cavities 3010 ofcartridge body 3000 . Thestaple driver 3060 is positioned to support thestaples 3042 therein (FIGS. 9 and 10) and to drive thestaples 3042 from thestaple cavity 3010 during the firing stroke. Due to the different patterns ofstaple cavities 3010 in thecartridge body 3000, eg,patterns 3020, 3022, and 3024, thestaple drivers 3060 can have different geometries and/or orientations. For example, thestaple drivers 3060 positioned in thestaple cavities 3010 of thefirst pattern 3020 may include a connected driver described in a US filing entitled "METHOD FORCREATING A FLEXIBLE STAPLE LINE" on September 26, 2014 Patent Application No. 14/498,145, now US Patent Application Publication 2016/0089142, the entire contents of which are incorporated herein by reference. Each connected driver may include an inner driver instaple cavities 3010 ininner row 3014a, an intermediate driver instaple cavities 3010 inmiddle row 3014b, and an outer driver instaple cavities 3010 inouter row 3014c. The connecting flange can connect the intermediate drive to the at least one internal drive and the at least one external drive. In other examples, the staple drivers positioned in the staple cavities in thefirst pattern 3020 may include separate drivers, where each driver drives a single staple. In other examples, the staples can be direct drive staples that can be actuated by direct contact with wedge slides and/or cam surfaces, as in the U.S. filing titled "SURGICAL STAPLES AND STAPLE CARTRIDGES" December 23, 2013 Described in Patent Application No. 14/138,475 (now US Patent Application Publication 2015/0173749) and US Patent Application No. 14/498,145, the entire contents of each of which are incorporated herein by reference.

被定位在钉腔3010中的驱动器3060的尺寸和位置设定成用于通过其滑动件和凸轮表面驱动接合。例如，驱动器3060被定位在第一图案 3020的钉腔3010中。近侧驱动器3060a，3060b，3060c和3060d分别被定位在近侧图案3022的钉腔3010a，3010b，3010c和3010d中，并且远侧驱动器3060e，3060f，3060g和3060h分别定位远侧图案3024的钉腔3010e， 3010f，3010g和3010h中。再次参见图4，滑动组件1120和其楔形凸轮 1122可被构造成能够提升钉腔3010中的钉驱动器3060。在所述实例中，凸轮1122被构造成能够沿仓体3000的长度驱动地接合驱动器3060。更具体地，凸轮1122最初接合并驱动近侧驱动器3060a，3060b，3060c和 3060d以击发近侧图案3022中的钉，然后接合并驱动驱动器3060以击发第一图案3022中的钉，并且最后接合并驱动远侧驱动器3060e，3060f， 3060g和3060h以击发远侧图案3024中的钉。尽管近侧驱动器3060a， 3060b，3060c和3060d和/或远侧驱动器3060e，3060f，3060g和3060h具有与钉腔3010的第一图案3020中的驱动器3060不同的几何结构，但是其滑动件和凸轮表面与仓体3000中的不同驱动器兼容。Thedriver 3060 positioned in thestaple cavity 3010 is sized and positioned for driving engagement through its slider and cam surfaces. For example, thedriver 3060 is positioned in thestaple cavity 3010 of thefirst pattern 3020.Proximal drivers 3060a, 3060b, 3060c, and 3060d are positioned instaple cavities 3010a, 3010b, 3010c, and 3010d, respectively, ofproximal pattern 3022, anddistal drivers 3060e, 3060f, 3060g, and 3060h, respectively, are positioned in staple cavities ofdistal pattern 3024, respectively 3010e, 3010f, 3010g and 3010h. Referring again to FIG. 4 , theslide assembly 1120 and itswedge cam 1122 can be configured to lift thestaple drivers 3060 in thestaple cavity 3010. In the illustrated example, thecam 1122 is configured to driveably engage thedriver 3060 along the length of thecartridge body 3000. More specifically, thecam 1122 initially engages and drives theproximal drivers 3060a, 3060b, 3060c and 3060d to fire the staples in theproximal pattern 3022, then engages and drives thedriver 3060 to fire the staples in thefirst pattern 3022, and finally engages and drives the staples in thefirst pattern 3022. Thedistal drivers 3060e, 3060f, 3060g, and 3060h are driven to fire the staples in thedistal pattern 3024. Although theproximal drivers 3060a, 3060b, 3060c and 3060d and/or thedistal drivers 3060e, 3060f, 3060g and 3060h have a different geometry than thedrivers 3060 in thefirst pattern 3020 of thestaple cavity 3010, their slider and cam surfaces Compatible with different drives in thecartridge body 3000.

再次参见图4，滑动组件1120包括四个凸轮表面1122。第一对凸轮表面1122定位成用于在纵向轴线LA的第一侧上与钉驱动器驱动接合，并且第二对凸轮表面1122定位成用于在纵向轴线LA的第二侧上与钉驱动器驱动接合。每对中的凸轮表面1122纵向偏置。在其他实例中，凸轮表面1122可纵向对准。每对凸轮表面1122被构造成能够提升三驱动器 (参见例如图81-83中的驱动器1170)，即，支撑钉腔3010的内排3014a 中的钉、钉腔3010的中间排3014b中的钉以及钉腔3010的外排3014c中的钉的连接的驱动器。凸轮表面1122还被构造成能够提升近侧驱动器 3060a，3060b，3060c和3060d以及远侧驱动器3060e，3060f，3060g和3060h。在其他实例中，滑动组件1120可包括多于或少于四个凸轮表面。Referring again to FIG. 4 , theslide assembly 1120 includes four cam surfaces 1122 . The first pair ofcam surfaces 1122 are positioned for driving engagement with the staple drivers on a first side of the longitudinal axis LA, and the second pair ofcam surfaces 1122 are positioned for driving engagement with the staple drivers on a second side of the longitudinal axis LA . The cam surfaces 1122 in each pair are longitudinally offset. In other examples, the cam surfaces 1122 may be longitudinally aligned. Each pair ofcam surfaces 1122 is configured to lift three drivers (see, eg,driver 1170 in FIGS. 81-83 ), ie, to support staples ininner row 3014a ofstaple cavities 3010 , staples inmiddle row 3014b ofstaple cavities 3010 , and The driver for the connection of the staples in theouter row 3014c of thestaple cavity 3010.Cam surface 1122 is also configured to liftproximal drivers 3060a, 3060b, 3060c and 3060d anddistal drivers 3060e, 3060f, 3060g and 3060h. In other examples,slide assembly 1120 may include more or less than four cam surfaces.

近侧驱动器3060a-3060d和远侧驱动器3060e-3060h是连接的驱动器 3058。示例性连接的驱动器3058在图13-16中示出。连接的驱动器3058 包括第一驱动器3060a和第二驱动器3060b。连接凸缘3068在两个驱动器3060a和3060b之间延伸。因为第一驱动器3060a和第二驱动器3060b 连接，所以由第一驱动器3060a和第二驱动器3060b支撑的钉由滑动组件同时击发。每个驱动器3060a和3060b还包括用于支撑钉的基部的托架 3070。引导件3062a和3062b分别从每个驱动器3060a和3060b侧向延伸。第一引导件3062a沿第一方向延伸并形成连接的驱动器3058的外侧部分，并且第二引导件3062b沿第二相反方向延伸并形成连接的驱动器 3058的内侧部分。分别在引导件3062a和3062b上的斜坡表面3064a和3064b定位成用于与滑动组件的凸轮表面驱动接触。当通过滑动组件运动到击发位置时，引导件3062a和3062b在仓体3000的通道3036(图6) 中被向上驱动。通道3036形成垂直支撑结构，引导件3062a，3062b被凸轮表面驱动通过该垂直支撑结构。如本文所述，凸轮表面可纵向偏置。Proximal drivers 3060a-3060d anddistal drivers 3060e-3060h areconnected drivers 3058. An exemplaryconnected driver 3058 is shown in Figures 13-16. Theconnected drivers 3058 include afirst driver 3060a and asecond driver 3060b. A connectingflange 3068 extends between the twodrivers 3060a and 3060b. Because thefirst driver 3060a and thesecond driver 3060b are connected, the staples supported by thefirst driver 3060a and thesecond driver 3060b are simultaneously fired by the slide assembly. Eachdriver 3060a and 3060b also includes abracket 3070 for supporting the base of the peg.Guides 3062a and 3062b extend laterally from eachdriver 3060a and 3060b, respectively. Afirst guide 3062a extends in a first direction and forms an outer portion of the connecteddriver 3058, and asecond guide 3062b extends in a second opposite direction and forms an inner portion of the connecteddriver 3058.Ramp surfaces 3064a and 3064b onguides 3062a and 3062b, respectively, are positioned for driving contact with the cam surfaces of the slide assembly. When moved to the firing position by the slide assembly, theguides 3062a and 3062b are driven upward in the channel 3036 (FIG. 6) of thecartridge body 3000. Thechannel 3036 forms a vertical support structure through which theguides 3062a, 3062b are driven by the cam surfaces. As described herein, the cam surfaces may be longitudinally offset.

在所述实例中，斜坡表面3064a，3064b相应地偏置，如图14和图 16中所示出的。在其他实例中，斜坡表面3064a和3064b可对准。In the example, theramp surfaces 3064a, 3064b are offset accordingly, as shown in FIGS. 14 and 16 . In other examples,ramp surfaces 3064a and 3064b may be aligned.

在其他实例中，钉仓中的近侧驱动器和/或远侧驱动器可不连接。例如，参见图12，示出了钉仓4800。钉仓体4800在许多方面类似于钉仓体 3000。例如，钉仓体4800包括成角度取向的钉腔的第一图案4820，其以人字形图案布置。狭槽4804沿仓体4800的纵向轴线LA延伸。钉仓体4800 还包括布置在近侧图案4822中的近侧钉腔和布置在远侧图案4824中的远侧钉腔。近侧图案4822包括在狭槽4804的第一侧上的第一对平行的、纵向对准的钉腔和在纵向狭槽4804的第二侧上的第二对平行的、纵向对准的钉腔。远侧图案4824还包括在狭槽4804的第一侧上的第一对平行的、纵向对准的钉腔和在纵向狭槽4804的第二侧上的第二对平行的、纵向偏置的钉腔。近侧图案4822和远侧图案4824相对于纵向轴线LA对称。在其他实例中，近侧图案4822和/或远侧图案4824可相对于纵向轴线LA 不对称。In other instances, the proximal driver and/or the distal driver in the staple cartridge may not be connected. For example, referring to Figure 12, astaple cartridge 4800 is shown.Cartridge body 4800 is similar tocartridge body 3000 in many respects. For example,staple cartridge body 4800 includes afirst pattern 4820 of angularly oriented staple cavities arranged in a herringbone pattern. Theslot 4804 extends along the longitudinal axis LA of thecartridge body 4800.Cartridge body 4800 also includes proximal staple cavities disposed inproximal pattern 4822 and distal staple cavities disposed indistal pattern 4824.Proximal pattern 4822 includes a first pair of parallel, longitudinally aligned staple cavities on a first side ofslot 4804 and a second pair of parallel, longitudinally aligned staples on a second side oflongitudinal slot 4804 cavity.Distal pattern 4824 also includes a first pair of parallel, longitudinally aligned staple cavities on a first side ofslot 4804 and a second pair of parallel, longitudinally offset cavities on a second side oflongitudinal slot 4804 Nail cavity.Proximal pattern 4822 anddistal pattern 4824 are symmetrical with respect to longitudinal axis LA. In other examples,proximal pattern 4822 and/ordistal pattern 4824 may be asymmetrical relative to longitudinal axis LA.

驱动器4860被定位在第一图案4820的钉腔4810中。如本文所述，第一图案4820的钉腔4810中的驱动器4860是三驱动器。近侧驱动器 4860a，4860b，4860c和4860d被定位在近侧图案4822的钉腔中，并且远侧驱动器4860e，4860f，4860g和4860h被定位在远侧图案4824的钉腔中。近侧驱动器4860a-4860d和远侧驱动器4860e-4860h是单个驱动器。示例性单个驱动器4860a和4860b在图17和图18中示出。Drivers 4860 are positioned in staple cavities 4810 offirst pattern 4820. As described herein, the drivers 4860 in the staple cavities 4810 of thefirst pattern 4820 are triple drivers.Proximal drivers 4860a, 4860b, 4860c, and 4860d are positioned in the staple cavities ofproximal pattern 4822, anddistal drivers 4860e, 4860f, 4860g, and 4860h are positioned in the staple cavities ofdistal pattern 4824.Proximal drivers 4860a-4860d anddistal drivers 4860e-4860h are a single driver. Exemplarysingle drivers 4860a and 4860b are shown in FIGS. 17 and 18 .

每个驱动器4860a和4860b包括用于支撑钉的基部的托架4870。引导件4862a和4862b分别从每个驱动器4860a和4860b侧向延伸。第一引导件4862a沿第一方向延伸并形成第一驱动器4860a的外侧部分，并且第二引导件4862b沿第二相反方向延伸并形成第二驱动器4860b的外侧部分。分别在引导件4862a和4862b上的斜坡表面4864a和4864b定位成用于与滑动组件的凸轮表面驱动接触。当驱动器4860a和4860b通过滑动组件运动到击发位置时，引导件4862a和4862b在仓体4800中的通道诸如仓3000(图6)中的通道3036中被向上驱动。通道形成垂直支撑结构，引导件4862a和4862b被凸轮表面驱动通过该垂直支撑结构。这种通道可稳定引导件4862a和4862b，并且因此在部署期间分别稳定各个驱动器 4860a和4860b。如本文所述，凸轮表面可纵向偏置。在所述实例中，斜坡表面4864a，4864b相应地偏置，如图18中所示。在其他实例中，斜坡表面4864a和4864b可对准。Eachdriver 4860a and 4860b includes abracket 4870 for supporting the base of the peg.Guides 4862a and 4862b extend laterally from eachdriver 4860a and 4860b, respectively. Thefirst guide 4862a extends in a first direction and forms an outer portion of thefirst driver 4860a, and thesecond guide 4862b extends in a second opposite direction and forms an outer portion of thesecond driver 4860b.Ramp surfaces 4864a and 4864b onguides 4862a and 4862b, respectively, are positioned for driving contact with the cam surfaces of the slide assembly. When thedrivers 4860a and 4860b are moved by the slide assembly to the firing position, theguides 4862a and 4862b are driven upward in channels in thecartridge body 4800, such aschannel 3036 in the cartridge 3000 (FIG. 6). The channels form a vertical support structure through which guides 4862a and 4862b are driven by the cam surfaces. Such channels may stabilizeguides 4862a and 4862b, and thusrespective actuators 4860a and 4860b, respectively, during deployment. As described herein, the cam surfaces may be longitudinally offset. In the example, theramp surfaces 4864a, 4864b are offset accordingly, as shown in FIG. 18 . In other examples,ramp surfaces 4864a and 4864b may be aligned.

因为第一驱动器4860a和第二驱动器4860b是分开的，所以由第一驱动器4860a和第二驱动器4860b支撑的钉可被独立地击发。在某些实例中，可顺序地击发第一驱动器4860a和第二驱动器4860b。例如，可有利地在外部钉之前击发内部钉，这可通过单独的驱动器4860a和4860b实现。在其他实例中，外部钉可在具有单独的驱动器4860a和4860b的内部钉之前被击发。例如，通过调节凸轮表面和斜坡表面3864a和4864b之间的关系可修改击发顺序。Because thefirst driver 4860a and thesecond driver 4860b are separate, the staples supported by thefirst driver 4860a and thesecond driver 4860b can be fired independently. In some instances, thefirst driver 4860a and thesecond driver 4860b can be fired sequentially. For example, the inner staples may advantageously be fired before the outer staples, which may be accomplished byseparate drivers 4860a and 4860b. In other examples, the outer staples may be fired before the inner staples withseparate drivers 4860a and 4860b. For example, the firing sequence can be modified by adjusting the relationship between the cam surfaces andramp surfaces 3864a and 4864b.

在各种实例中，远侧图案和/或近侧图案中的钉腔可不是纵向对准的和/或可不是平行的。例如，现在参见图19和图20，示出了钉仓体4600。钉仓体4600在许多方面类似于钉仓体3000。例如，钉仓体4600包括成角度取向的钉腔4610的第一图案4620，其以人字形图案布置。狭槽4604 沿仓体4600的纵向轴线LA延伸穿过钉仓体4600的平台4602。钉仓体 4600还包括布置在近侧图案4622中的近侧钉腔4610a-4610d和布置在远侧图案4624中的远侧钉腔4610e-4610h。近侧图案4622包括在狭槽4604 的第一侧上的第一对平行的、纵向偏置的钉腔4610a，4610b和在纵向狭槽4604的第二侧上的第二对平行的、纵向偏置的钉腔4610c，4610d。远侧图案4624还包括在狭槽4604的第一侧上的第一对平行的、纵向偏置的钉腔4610e，4610f和在纵向狭槽4604的第二侧上的第二对平行的、纵向偏置的钉腔4610g，4610h。近侧图案4622和远侧图案4624相对于纵向轴线LA对称。在其他实例中，近侧图案4622和远侧图案4624可相对于纵向轴线LA不对称。In various examples, the staple cavities in the distal pattern and/or the proximal pattern may not be longitudinally aligned and/or may not be parallel. For example, referring now to Figures 19 and 20, astaple cartridge body 4600 is shown. Thestaple cartridge body 4600 is similar to thestaple cartridge body 3000 in many respects. For example,staple cartridge body 4600 includes afirst pattern 4620 of angularly orientedstaple cavities 4610 arranged in a herringbone pattern. Theslot 4604 extends through theplatform 4602 of thecartridge body 4600 along the longitudinal axis LA of thecartridge body 4600.Cartridge body 4600 also includesproximal staple cavities 4610a-4610d arranged inproximal pattern 4622 anddistal staple cavities 4610e-4610h arranged indistal pattern 4624. Theproximal pattern 4622 includes a first pair of parallel, longitudinally offsetstaple cavities 4610a, 4610b on a first side of theslot 4604 and a second pair of parallel, longitudinally offset staple cavities on a second side of thelongitudinal slot 4604.Positioned staple cavities 4610c, 4610d.Distal pattern 4624 also includes a first pair of parallel, longitudinally offsetstaple cavities 4610e, 4610f on a first side ofslot 4604 and a second pair of parallel, longitudinally offset, on a second side oflongitudinal slot 4604 Offsetstaple cavities 4610g, 4610h. Theproximal pattern 4622 and thedistal pattern 4624 are symmetrical with respect to the longitudinal axis LA. In other examples, theproximal pattern 4622 and thedistal pattern 4624 can be asymmetric with respect to the longitudinal axis LA.

连接的驱动器4658被定位在近侧钉腔和远侧钉腔4610a-4610h中。示例性连接的驱动器4658在图21-24中示出。连接的驱动器4658包括第一驱动器4660a和第二驱动器4660b。连接凸缘4668在两个偏置驱动器 4660a和4660b之间延伸。因为驱动器4660a和4660b连接，所以由驱动器4660a，4660b支撑的钉被滑动组件同时击发。每个驱动器4660a和4660b 包括用于支撑钉的基部的托架4670。引导件4662a和4662b分别从每个驱动器4660a和4660b侧向延伸。第一引导件4662a沿第一方向延伸并形成连接的驱动器4658的外侧部分，并且第二引导件4662b沿第二相反方向延伸并形成连接的驱动器4658的内侧部分。分别在引导件4662a和 4662b上的斜面4664a和4664b定位成用于与滑动组件的凸轮表面驱动接触。例如，当驱动器4660a，4660b通过滑动组件运动到击发位置时，引导件4662a和4662b在仓体4800中的通道诸如钉仓3000(图6)中的通道3036中被向上驱动。通道形成垂直支撑结构，当引导件4662a，4662b 由凸轮表面驱动时，引导件4662a，4662b通过该垂直支撑结构被支撑。如本文所述，凸轮表面可纵向偏置。在所述实例中，斜坡表面4664a，4664b 相应地偏置，如图22和图24中所示出的。在其他实例中，斜坡表面4664a 和4664b可对准。Connected drivers 4658 are positioned in the proximal anddistal staple cavities 4610a-4610h. An exemplaryconnected driver 4658 is shown in Figures 21-24. Theconnected drivers 4658 include afirst driver 4660a and asecond driver 4660b. A connectingflange 4668 extends between the two offsetdrivers 4660a and 4660b. Because thedrivers 4660a and 4660b are connected, the staples supported by thedrivers 4660a, 4660b are simultaneously fired by the slide assemblies. Eachdriver 4660a and 4660b includes abracket 4670 for supporting the base of the peg.Guides 4662a and 4662b extend laterally from eachdriver 4660a and 4660b, respectively. Thefirst guide 4662a extends in a first direction and forms an outer portion of the connecteddriver 4658 , and thesecond guide 4662b extends in a second opposite direction and forms an inner portion of the connecteddriver 4658 .Bevels 4664a and 4664b onguides 4662a and 4662b, respectively, are positioned for driving contact with the cam surfaces of the slide assembly. For example, when thedrivers 4660a, 4660b are moved by the slide assembly to the firing position, theguides 4662a and 4662b are driven upward in channels in thecartridge body 4800, such aschannel 3036 in the staple cartridge 3000 (FIG. 6). The channels form a vertical support structure by which theguides 4662a, 4662b are supported as they are driven by the cam surfaces. As described herein, the cam surfaces may be longitudinally offset. In the example, theramp surfaces 4664a, 4664b are offset accordingly, as shown in FIGS. 22 and 24 . In other examples,ramp surfaces 4664a and 4664b may be aligned.

现在参见图25和图26，示出了钉仓体4700。钉仓体4700在许多方面类似于钉仓体3000。例如，钉仓体4700包括成角度取向的钉腔4710 的第一图案4720，其以人字形图案布置。狭槽4704沿仓体4700的纵向轴线LA延伸穿过钉仓体4700的平台4702。钉仓体4700还包括布置在近侧图案4722中的近侧钉腔4710a-4710f。近侧图案4722包括内部钉腔4710c 和4710d，其被取向成平行于纵向轴线LA。近侧图案4722还包括成角度取向的外部钉腔4710a和4710f，以及成角度取向的中间腔4710b和4710e。外部钉腔4710a和4710f以及中间钉腔4710b和4710e相对于纵向轴线LA 以倾斜角取向。成角度取向的外部钉腔4710a和4710f也相对于第一图案 4720中的钉腔4710的腔轴线以倾斜角取向。外部钉腔4710a和4710f的角度小于第一图案4720中的钉腔4710的角度。换句话说，外部钉腔4710a 和4710f以比第一图案4720中的钉腔4710更接近于与纵向轴线LA平行的角度取向。在所述实例中，近侧图案4722可比第一图案4720具有更小的柔性。Referring now to Figures 25 and 26, astaple cartridge body 4700 is shown. Thestaple cartridge body 4700 is similar to thestaple cartridge body 3000 in many respects. For example, thestaple cartridge body 4700 includes afirst pattern 4720 of angularly orientedstaple cavities 4710 arranged in a herringbone pattern. Theslot 4704 extends through theplatform 4702 of thecartridge body 4700 along the longitudinal axis LA of thecartridge body 4700.Cartridge body 4700 also includesproximal staple cavities 4710a - 4710f disposed inproximal pattern 4722 .Proximal pattern 4722 includesinner staple cavities 4710c and 4710d, which are oriented parallel to longitudinal axis LA. Theproximal pattern 4722 also includes angularly orientedouter staple cavities 4710a and 4710f, and angled orientedintermediate cavities 4710b and 4710e. Theouter staple cavities 4710a and 4710f and themiddle staple cavities 4710b and 4710e are oriented at an oblique angle with respect to the longitudinal axis LA. The angularly orientedouter staple cavities 4710a and 4710f are also oriented at an oblique angle relative to the lumen axis of thestaple cavities 4710 in thefirst pattern 4720. The angle of theouter staple cavities 4710a and 4710f is less than the angle of thestaple cavities 4710 in thefirst pattern 4720. In other words, theouter staple cavities 4710a and 4710f are oriented at an angle that is closer to parallel with the longitudinal axis LA than thestaple cavities 4710 in thefirst pattern 4720. In the example, theproximal pattern 4722 may be less flexible than thefirst pattern 4720.

中间钉腔4710b和4710e被取向成平行于第一图案4020中的某些钉腔4710。例如，中间钉腔4710b和4710e被取向成平行于第一图案4720 中的内排中的钉腔4710。尽管近侧图案4722中的某些钉腔没有与第一图案4020中的钉腔成角度地偏置，但是当被视为整体时，近侧图案4722 不同于第一图案4020并且不同于第一图案4020内的纵向重复的子区域。Themiddle staple cavities 4710b and 4710e are oriented parallel to some of thestaple cavities 4710 in thefirst pattern 4020. For example, themiddle staple cavities 4710b and 4710e are oriented parallel to thestaple cavities 4710 in the inner row in thefirst pattern 4720. Although some staple cavities inproximal pattern 4722 are not angularly offset from staple cavities infirst pattern 4020,proximal pattern 4722 is different fromfirst pattern 4020 and different fromfirst pattern 4020 when viewed as a whole Vertically repeating sub-regions withinpattern 4020.

近侧图案4722包括被定位在狭槽4704的每个侧面上的三个钉腔。在其他实例中，可在狭槽4704的一侧或两侧上的近侧图案4722中布置少于三个钉腔或多于三个钉腔。近侧图案4722不包括纵向重复的子图案。在其他实例中，近侧图案4722可以是纵向重复的。另外，近侧图案 4722相对于纵向轴线LA对称。在其他实例中，近侧图案4722可相对于纵向轴线LA不对称。Theproximal pattern 4722 includes three staple cavities positioned on each side of theslot 4704. In other examples, less than three staple cavities or more than three staple cavities may be arranged inproximal pattern 4722 on one or both sides ofslot 4704. Theproximal pattern 4722 does not include longitudinally repeating sub-patterns. In other examples,proximal pattern 4722 may be longitudinally repeating. Additionally,proximal pattern 4722 is symmetrical with respect to longitudinal axis LA. In other examples, theproximal pattern 4722 can be asymmetric relative to the longitudinal axis LA.

驱动器4760被定位在仓体4700中的钉腔4710中。如本文所述，第一图案4720的钉腔4710中的驱动器4760是三驱动器。近侧驱动器4760a， 4760b，4760c，4760d，4710e和4710f分别被定位在近侧图案4722的近侧钉腔4710a，4710b，4710c，4710d，4710e和4710f中。近侧驱动器4760a-4760f 是单个驱动器。在某些实例中，内腔4710c和4710d中的近侧驱动器4760c 和4760d可分别是单个驱动器，近侧驱动器4760a和4760b可以是连接的驱动器，并且近侧驱动器4760e和4760f可以是连接的驱动器。在其他实例中，近侧驱动器4760a，4760b和4760c可包括第一连接的驱动器，并且远侧驱动器4760d，4760e和4760f可包括第二连接的驱动器。Driver 4760 is positioned instaple cavity 4710 incartridge body 4700. As described herein, thedrivers 4760 in thestaple cavities 4710 of thefirst pattern 4720 are triple drivers.Proximal drivers 4760a, 4760b, 4760c, 4760d, 4710e, and 4710f are positioned inproximal staple cavities 4710a, 4710b, 4710c, 4710d, 4710e, and 4710f, respectively, ofproximal pattern 4722. The proximal drives 4760a-4760f are single drives. In some examples,proximal drivers 4760c and 4760d inlumens 4710c and 4710d can be a single driver, respectively,proximal drivers 4760a and 4760b can be connected drivers, andproximal drivers 4760e and 4760f can be connected drivers. In other examples,proximal drivers 4760a, 4760b, and 4760c can include a first connected driver, anddistal drivers 4760d, 4760e, and 4760f can include a second connected driver.

读者将理解，本文描述的钉腔的各种图案可组合和/或互换。在某些实例中，钉腔的一个或多个不规则图案可限定在钉仓体的近侧端部和/ 或远侧端部处。除此之外或另选地，可将一个或多个不规则图案或次图案夹在或插入主图案内。The reader will understand that the various patterns of staple cavities described herein may be combined and/or interchanged. In certain instances, one or more irregular patterns of staple cavities can be defined at the proximal and/or distal ends of the staple cartridge body. Additionally or alternatively, one or more irregular patterns or sub-patterns may be sandwiched or inserted within the main pattern.

钉线中的钉的角度取向可影响缝合组织沿钉线的柔性或顺应性。例如，当钉相对于纵向轴线和/或切割线以倾斜角取向时，钉线的柔性可增加。这种角度取向可响应于沿切割线和/或邻近切割线的力诸如张力和/ 或扭转而在一定限度内提供柔性或可扩展性。更具体地，钉线的柔性可允许缝合组织的拉伸、弯曲、折叠和/或扭曲。通常，当钉的角度取向相对于钉线和/或切割线的纵向轴线接近45度或135度时，缝合组织的柔性增加。例如，由成角度取向的钉构成的钉线可被认为是柔顺的或弹性的钉线。The angular orientation of the staples in the staple line can affect the flexibility or compliance of the stapled tissue along the staple line. For example, the flexibility of the staple line may be increased when the staples are oriented at an oblique angle relative to the longitudinal axis and/or cutting line. Such angular orientation may provide flexibility or expandability within certain limits in response to forces such as tension and/or torsion along and/or adjacent the cutting line. More specifically, the flexibility of the staple line may allow for stretching, bending, folding and/or twisting of the stapled tissue. Typically, the flexibility of the stapled tissue increases as the angular orientation of the staples approaches 45 degrees or 135 degrees relative to the longitudinal axis of the staple line and/or cut line. For example, a staple line composed of angularly oriented staples may be considered a compliant or elastic staple line.

在某些实例中，钉线的柔性可相对于切割线侧向变化。例如，钉线的第一部分中的一个或多个钉可相对于切割线以第一角度取向，并且钉线的第二部分中的一个或多个钉可相对于切割线以不同的角度取向。钉线的第一部分可具有第一柔性，并且钉线的第二部分可具有不同的柔性。在某些实例中，第一部分可与第二部分侧向偏置。例如，钉线的第一部分可包括第一钉排或第一排的一部分，并且钉线的第二部分可包括第二钉排或第二排的一部分。在所述实例中，沿第一钉排的钉线的柔性可不同于沿第二钉排的钉线的柔性。In certain instances, the flexibility of the staple line can vary laterally relative to the cutting line. For example, one or more staples in a first portion of the staple line may be oriented at a first angle relative to the cut line, and one or more staples in a second portion of the staple line may be oriented at a different angle relative to the cut line. The first portion of the staple line can have a first flexibility, and the second portion of the staple line can have a different flexibility. In some instances, the first portion can be laterally offset from the second portion. For example, a first portion of the line of staples can include a first row of staples or a portion of a first row, and a second portion of the line of staples can include a second row of staples or a portion of a second row. In the example, the flexibility of the staple line along the first staple row may be different from the flexibility of the staple line along the second staple row.

现在参见图27，示出了钉仓体3200的一部分。钉仓体3200包括平台3202和纵向狭槽3204。纵向狭槽3204沿纵向轴线LA延伸。钉腔3210 限定在钉仓体3200中，并且每个钉腔3210在平台3202中限定开口3212。钉3242被定位在每个钉腔3210中。钉3242在许多方面可类似于钉3042 (图10)或钉3142(图11)。在某些实例中，每个钉3242的腿部可偏置抵靠钉腔3210的内壁。读者将理解，钉腔3210中的钉3242的布置对应于当钉3242从钉仓体3200被击发并进入组织时钉3242在钉线中的布置。更具体地，所得到的钉线中的每个钉3242的基部与腔轴线CA共线或基本上共线。Referring now to FIG. 27, a portion of thestaple cartridge body 3200 is shown. Thecartridge body 3200 includes aplatform 3202 and alongitudinal slot 3204. Thelongitudinal slot 3204 extends along the longitudinal axis LA.Staple cavities 3210 are defined in thestaple cartridge body 3200 , and eachstaple cavity 3210 defines anopening 3212 in theplatform 3202 . Astaple 3242 is positioned in eachstaple cavity 3210.Staples 3242 may be similar in many respects to staples 3042 (FIG. 10) or staples 3142 (FIG. 11). In some examples, the legs of each staple 3242 can be biased against the inner wall of thestaple cavity 3210. The reader will understand that the placement of thestaples 3242 in thestaple cavity 3210 corresponds to the placement of thestaples 3242 in the staple line when thestaples 3242 are fired from thestaple cartridge body 3200 and into tissue. More specifically, the base of each staple 3242 in the resulting staple line is collinear or substantially collinear with the lumen axis CA.

钉腔开口3212在纵向狭槽3204的第一侧上被布置成三个排3214a， 3214b和3214c。内开口3212a限定内排3214a中的内腔3210a的周边，中间开口3212b限定中间排3214b中的中间腔3210b的周边，并且外开口3212c限定外排3214c中的外腔3210c的周边。内部钉3242a被定位在内腔3210a中，中间钉3242b被定位在中间腔3210b中，并且外部钉3242c被定位在外腔3210c中。尽管未在图27中示出，在至少一个实例中，狭槽3204的相对侧上的钉腔3210形成纵向狭槽3204的第一侧上的钉腔 3210的镜像反射。因此，在所得到的钉线中的钉3242的布置相对于切割线对称。在其他实例中，钉线可相对于切割线不对称。Thestaple cavity openings 3212 are arranged on a first side of thelongitudinal slot 3204 in threerows 3214a, 3214b and 3214c. The inner opening 3212a defines the perimeter of theinner cavity 3210a in theinner row 3214a, themiddle opening 3212b defines the perimeter of themiddle cavity 3210b in themiddle row 3214b, and theouter opening 3212c defines the perimeter of theouter cavity 3210c in theouter row 3214c.Inner staples 3242a are positioned ininner lumen 3210a,middle staples 3242b are positioned inmiddle lumen 3210b, andouter staples 3242c are positioned inouter lumen 3210c. Although not shown in FIG. 27 , in at least one example, thestaple cavities 3210 on opposite sides of theslot 3204 form a mirror image of thestaple cavities 3210 on the first side of thelongitudinal slot 3204. Thus, the arrangement ofstaples 3242 in the resulting staple line is symmetrical relative to the cut line. In other examples, the staple line may be asymmetric relative to the cut line.

每个钉腔开口3212具有第一端部或近侧端部3216和第二端部或远侧端部3218。腔轴线CA在每个开口3212的近侧端部3216和远侧端部 3218之间延伸。每个相应排中的钉腔开口3212是平行的。例如，内腔 3210a相对于纵向轴线LA以角度A取向。换句话说，内开口3212a的腔轴线(例如，CA_A1和CA_A2)相对于纵向轴线LA以角度A取向。中间腔 3210b相对于纵向轴线LA以角度B取向。换句话说，中间开口3212b的腔轴线(例如，CA_B1和CA_B2)相对于纵向轴线LA以角度B取向。外腔 3210c相对于纵向轴线LA以角度C取向。换句话说，由外开口3212限定的腔轴线(例如，CA_C1和CA_C2)相对于纵向轴线LA以角度C取向。Eachstaple cavity opening 3212 has a first orproximal end 3216 and a second ordistal end 3218. The lumen axis CA extends between theproximal end 3216 and thedistal end 3218 of eachopening 3212. Thestaple cavity openings 3212 in each respective row are parallel. For example,lumen 3210a is oriented at angle A relative to longitudinal axis LA. In other words, the lumen axes (eg, CA_A1 and CA_A2 ) of the inner opening 3212a are oriented at an angle A relative to the longitudinal axis LA. Theintermediate cavity 3210b is oriented at an angle B relative to the longitudinal axis LA. In other words, the lumen axes (eg, CA_B1 and CA_B2 ) of theintermediate opening 3212b are oriented at an angle B relative to the longitudinal axis LA. Theouter lumen 3210c is oriented at an angle C relative to the longitudinal axis LA. In other words, the lumen axes (eg, CA_C1 and CA_C2 ) defined by theouter opening 3212 are oriented at an angle C relative to the longitudinal axis LA.

角度A、B和C是不同的。因此，内开口3212a相对于外开口3212c 倾斜地取向。因为外开口3212c的腔轴线CA(例如，轴线CA_C1和CA_C2) 不平行于内开口3212a的腔轴线(例如，轴线CA_A1和CA_A2)，钉仓体 3200中的开口3212形成修改的或倾斜的人字形图案。中间开口3212b的腔轴线CA_B1和CA_B2可取向成垂直于或基本上垂直于内开口3212a或外开口3212c。例如，角度B可以是角度A或角度C的补角。在其他实例中，角度B可不是角度A或角度C的补角。Angles A, B and C are different. Accordingly, the inner opening 3212a is oriented obliquely with respect to theouter opening 3212c. Because the lumen axis CA (eg, axes CA_C1 and CA_C2 ) of theouter opening 3212c is not parallel to the lumen axis (eg, axes CA_A1 and CA_A2 ) of the inner opening 3212a, theopening 3212 in thecartridge body 3200 forms a modified or Slanted herringbone pattern. The lumen axes CA_B1 and CA_B2 of theintermediate opening 3212b may be oriented perpendicular or substantially perpendicular to the inner opening 3212a or theouter opening 3212c. For example, angle B may be the supplement of angle A or angle C. In other examples, angle B may not be the supplement of angle A or angle C.

由于角度A、B和C不同，钉线中的钉排的宽度W_A、W_B、W_C可不同。例如，内部钉3242a形成具有宽度W_A的钉排，中间钉3242b形成具有宽度W_B的钉排，并且外部钉3242c形成具有宽度W_C的钉排。宽度 W_A和W_C是不同的，因为角度A不同于角度C。在某些实例中，宽度W_B不同于宽度W_A和W_C。在其他实例中，宽度W_B可匹配宽度W_A或 W_C中的一个。例如，如果角度B是角度A的补角，则宽度W_B与宽度 W_A匹配。类似地，如果角度B是角度C的补角，则宽度W_B与宽度W_C匹配。Because the angles_A ,_B , and_C are different, the widths WA, WB, WC of the rows of staples in the staple line can vary. For example,inner staples 3242a form a row of staples having width WA, middle staples_3242b form_a row of staples having width WB, and outer staples_3242c form a row of staples having width WC. The widths W_A and W_C are different because angle A is different from angle C. In some instances, width_WB is different from widths_WA and_WC . In other examples, width_WB may match one of widths_WA or_WC . For example, if angle_B is the supplement of angle_A , then width WB matches width WA. Similarly, if angle_B is the supplement of angle_C , then width WB matches width WC.

此外，由于角度A、B和C不同，钉3242a，3242b和3242c的纵向长度L_A、L_B和L_C分别不同。例如，内部钉3242a具有纵向长度L_A，中间钉3242b具有纵向长度L_B，并且外部钉3242c具有纵向长度L_C。纵向长度L_A和L_C是不同的，因为角度A不同于角度C。因为纵向长度L_A和L_C不同，所以内部钉3242a相对于外部钉3242c至少部分地纵向交错或偏置。换句话说，每个内部钉3242a的至少一个端部不与外部钉3242b 的对应端部对准。因为端部不对准，所以相对于中间钉3242b的纵向重叠和/或间隙在内部钉3242a和外部钉3242c之间不同。在某些实例中，纵向长度L_B不同于长度L_A和L_C。在其他实例中，纵向长度L_B可与纵向长度L_A或L_C中的一个匹配。例如，如果角度B是角度A的补角，则纵向长度L_B与纵向长度L_A匹配。类似地，如果角度B是角度C的补角，则纵向长度L_B与纵向长度L_C匹配。Furthermore, due to the different angles_A ,_B and_C , the longitudinal lengths LA, LB and LC of thestaples 3242a, 3242b and 3242c are different, respectively. For example,inner staple 3242a has a longitudinal length LA, middle staple_3242b has a longitudinal length LB, and outer staple_3242c has a longitudinal length_LC . The longitudinal lengths LA and_LC are different because angle_A is different from angle C. Because the longitudinal lengths LA and_LC are different, the inner staples_3242a are at least partially longitudinally staggered or offset relative to theouter staples 3242c. In other words, at least one end of eachinner staple 3242a is not aligned with the corresponding end ofouter staple 3242b. Because the ends are not aligned, the longitudinal overlap and/or clearance relative to themiddle staples 3242b differs between theinner staples 3242a and theouter staples 3242c. In some instances, longitudinal length_LB differs from lengths LA and_LC_. In other examples, longitudinal length_LB may match one of longitudinal lengths LA or_LC_. For example, if angle_B is a supplement to angle_A , then longitudinal length LB matches longitudinal length LA. Similarly, if angle_B is a supplement to angle_C , then longitudinal length LB matches longitudinal length LC.

钉基部的长度也可影响宽度W_A、W_B和W_C以及纵向长度L_A、L_B和 L_C。在钉仓体3200中，内部钉3242a、中间钉3242b和外部钉3242c具有相同长度的基部。例如，相同的钉可被定位在每个钉腔3210中。在其他实例中，如本文进一步描述的，例如，具有不同几何结构和/或尺寸诸如不同长度的基部的钉可被定位在仓体中的某些钉腔中。The length of the nail base can also affect the widths_WA ,_WB and_WC and the longitudinal lengths LA,_LB and_LC_. Instaple cartridge body 3200,inner staples 3242a,middle staples 3242b, andouter staples 3242c have bases of the same length. For example, the same staples can be positioned in eachstaple cavity 3210. In other examples, as further described herein, for example, staples having bases of different geometries and/or sizes, such as different lengths, may be positioned in certain staple cavities in the cartridge body.

仍然参见图27，钉腔3210a，3210b和3210c的角度取向以及对应的宽度W_A、W_B和W_C以及纵向长度L_A、L_B和L_C分别可影响钉线中的侧向和纵向重叠量。钉3242之间的纵向和侧向重叠还取决于钉腔3210的间距。通常，相邻钉之间的较大重叠对应于较不直接的流体路径，这可对应于更大的组织密封特性。更大的重叠也会降低钉线的柔性，因为组织可在重叠区域中受到更多约束。此外，更大的重叠可对应于钉之间的更小间距。在某些实例中，可希望改变钉线中的侧向和/或纵向重叠的程度。随着重叠变化，钉线的柔性和密封特性也可变化。Still referring to Figure 27, the angular orientation of staple_cavities_3210a ,_3210b , and_3210c and corresponding_widths WA, WB, and WC and longitudinal lengths LA, LB, and_LC , respectively, can affect lateral and longitudinal overlap in the staple line quantity. The longitudinal and lateral overlap betweenstaples 3242 also depends on the spacing ofstaple cavities 3210. Generally, greater overlap between adjacent staples corresponds to less direct fluid paths, which may correspond to greater tissue sealing properties. Greater overlap also reduces the flexibility of the staple line, as the tissue may be more constrained in the overlapping area. Additionally, greater overlap may correspond to smaller spacing between staples. In certain instances, it may be desirable to vary the degree of lateral and/or longitudinal overlap in the staple line. As the overlap varies, the flexibility and sealing properties of the staple line can also vary.

例如，本文描述的重叠或重叠程度可指正重叠或负重叠。当钉和/ 或钉排限定负重叠时，钉和/或钉排可间隔，使得他们不重叠并且在他们之间限定间隙。在其他实例中，钉或钉排可对准，使得重叠等于钉的直径。For example, the overlap or degree of overlap described herein can refer to positive or negative overlap. When the staples and/or rows of staples define a negative overlap, the staples and/or rows of staples can be spaced such that they do not overlap and define a gap between them. In other examples, the staples or rows of staples can be aligned such that the overlap is equal to the diameter of the staples.

读者将进一步理解，相对于钉仓中的钉或钉排的重叠程度对应于相对于钉仓中的钉腔或钉腔排的重叠程度。例如，钉或钉排之间的侧向和/ 或纵向重叠的相对差异对应于钉仓中的钉腔或钉腔排的侧向和/或纵向重叠的相对差异。在某些实例中，钉腿的至少一部分可定位成抵靠钉腔的近侧端部和远侧端部处的钉腔的内壁和/或偏置到其中。在所述实例中，相对于钉的外边缘测量的距离等于相对于对应钉腔的内边缘测量的距离。在其他实例中，这些距离之间的差异可以是最小的或无关紧要的。The reader will further understand that the degree of overlap relative to the staples or rows of staples in the staple cartridge corresponds to the degree of overlap relative to the staple cavities or rows of staple cavities in the staple cartridge. For example, a relative difference in lateral and/or longitudinal overlap between staples or rows of staples corresponds to a relative difference in lateral and/or longitudinal overlap of staple cavities or rows of staple cavities in a staple cartridge. In certain instances, at least a portion of the staple legs may be positioned against and/or biased into inner walls of the staple cavity at the proximal and distal ends of the staple cavity. In the example, the distance measured relative to the outer edge of the staple is equal to the distance measured relative to the inner edge of the corresponding staple cavity. In other instances, the difference between these distances may be minimal or insignificant.

在某些实例中，可使重叠程度最小化，诸如当钉的端部对准时。当钉的端部对准时，重叠与钉的直径相等或基本上相等。例如，如果钉由直径为约0.0079英寸的线材构成，则重叠可为约0.0079英寸。在其他实例中，重叠可小于钉的直径。例如，重叠可小于约0.0079英寸。在其他实例中，重叠程度可以是非重叠或负重叠，即，钉的端部之间的空间或间隙。在其他实例中，最小化的重叠可等于或小于钉长度的三分之一。例如，重叠可小于钉长度的33％。在其他实例中，重叠可小于钉长度的 25％或小于钉长度的10％。在其他实例中，例如，重叠可以是钉长度的 33％以上。In some instances, the degree of overlap can be minimized, such as when the ends of the staples are aligned. When the ends of the staples are aligned, the overlap is equal or substantially equal to the diameter of the staples. For example, if the staples are constructed of wire having a diameter of about 0.0079 inches, the overlap may be about 0.0079 inches. In other examples, the overlap may be less than the diameter of the staple. For example, the overlap may be less than about 0.0079 inches. In other examples, the degree of overlap may be non-overlapping or negative overlap, ie, the space or gap between the ends of the staples. In other examples, the minimized overlap may be equal to or less than one third of the staple length. For example, the overlap may be less than 33% of the staple length. In other examples, the overlap may be less than 25% of the staple length or less than 10% of the staple length. In other instances, for example, the overlap may be more than 33% of the staple length.

在某些实例中，钉线可包括内部钉排和中间钉排之间的第一重叠程度以及中间钉排和外部钉排之间的第二重叠程度。第二重叠程度可与侧向和/或纵向方向上的第一重叠程度不同。因此，钉线的内部部分可包括与钉线的外部部分不同的柔性。此外，内部部分的组织密封特性可不同于外部部分的组织密封特性。In certain examples, the staple line may include a first degree of overlap between the inner row of staples and the middle row of staples and a second degree of overlap between the middle row of staples and the outer row of staples. The second degree of overlap may be different from the first degree of overlap in the lateral and/or longitudinal direction. Thus, the inner portion of the staple wire may include a different flexibility than the outer portion of the staple wire. Furthermore, the tissue sealing properties of the inner portion may be different from the tissue sealing properties of the outer portion.

再次参见图27，角度A小于角度C。因此，宽度W_A小于宽度W_C，并且长度L_A大于长度L_C。例如，角度A可以是35度至40度，并且角度C可以是例如43度至47度。在其他实例中，角度A可小于35度或大于40度和/或角度C可小于43度或大于47度。角度A和角度C之间的差值可在三度至十二度之间。例如，差值可以是约八度。在其他实例中，角度A和角度C之间的差值可小于三度或大于十二度。Referring again to Figure 27, angle A is less than angle C. Thus, width_WA is less than width_WC and length LA is greater than length_LC_. For example, angle A may be 35 degrees to 40 degrees, and angle C may be, for example, 43 degrees to 47 degrees. In other examples, angle A may be less than 35 degrees or greater than 40 degrees and/or angle C may be less than 43 degrees or greater than 47 degrees. The difference between angle A and angle C may be between three and twelve degrees. For example, the difference may be about an octave. In other examples, the difference between angle A and angle C may be less than three degrees or greater than twelve degrees.

仍然参见图27，每个相应排中的钉3242对准。更具体地，内部钉 3242a的近侧端部纵向对准，内部钉3242a的远侧端部纵向对准，中间钉 3242b的近侧端部纵向对准，中间钉3242b的远侧端部纵向对准，外部钉 3242c的近侧端部纵向对准，并且外部钉3242c的远侧端部纵向对准。钉腔3310的每个排3214a，3214b和3214c中的对准的钉3242被构造成能够在钉线中形成多排对准的钉3242。由于钉3242的角度取向和它们之间的间距，钉排3242侧向重叠。内部钉3242a通过侧向重叠Y_A/B与中间钉3242b 侧向重叠，并且外部钉3242c通过侧向重叠Y_B/C与中间钉3242b侧向重叠。内部钉3242a和中间钉3242b之间的侧向重叠Y_A/B大于外部钉3242c 和中间钉3242b之间的侧向重叠Y_B/C。在所述实例中，相比于内部钉定位到中间钉，外部钉定位成更靠近中间钉。在其他实例中，侧向重叠Y_A/B可小于或等于侧向重叠Y_B/C。Still referring to Figure 27, thestaples 3242 in each respective row are aligned. More specifically, the proximal ends of theinner staples 3242a are longitudinally aligned, the distal ends of theinner staples 3242a are longitudinally aligned, the proximal ends of theintermediate staples 3242b are longitudinally aligned, and the distal ends of theintermediate staples 3242b are longitudinally aligned. In alignment, the proximal ends of theouter staples 3242c are longitudinally aligned, and the distal ends of theouter staples 3242c are longitudinally aligned. The alignedstaples 3242 in eachrow 3214a, 3214b, and 3214c of thestaple cavity 3310 are configured to form multiple rows of alignedstaples 3242 in a staple line. The rows ofstaples 3242 overlap laterally due to the angular orientation of thestaples 3242 and the spacing between them. Theinner staples 3242a laterally overlap themiddle staples 3242b by a lateral overlap Y_A/B , and theouter staples 3242c laterally overlap themiddle staples 3242b by a lateral overlap Y_B/C . The lateral overlap Y_A/B between theinner staples 3242a and themiddle staples 3242b is greater than the lateral overlap Y_B/C between theouter staples 3242c and themiddle staples 3242b . In the example, the outer staples are positioned closer to the middle staples than the inner staples are positioned to the middle staples. In other examples, the lateral overlap Y_A/B may be less than or equal to the lateral overlap Y_B/C .

中间钉3242b相对于内部钉3242a和外部钉3242c纵向交错。具体地，每个中间钉3242b在相邻的内部钉3242a之间纵向等距地定位并且在相邻的外部钉3242c之间纵向等距地定位。由于钉3242的角度取向和它们之间的间距，钉3242不纵向重叠。内部钉3242a与中间钉3242b间隔纵向间隙X_A/B，并且外部钉3242c与中间钉3242b间隔纵向间隙X_B/C。内部钉3242a和中间钉3242b之间的纵向间隙X_A/B小于外部钉3242c和中间钉 3242b之间的纵向间隙X_B/C。在其他实例中，纵向间隙X_A/B可大于或等于纵向间隙X_B/C。在某些实例中，中间钉3242b可与内部钉3242a和/或外部钉3242c纵向地重叠。Themiddle staples 3242b are longitudinally staggered relative to theinner staples 3242a andouter staples 3242c. Specifically, eachintermediate staple 3242b is positioned longitudinally equidistant between adjacentinner staples 3242a and longitudinally equidistant between adjacentouter staples 3242c. Due to the angular orientation of thestaples 3242 and the spacing between them, thestaples 3242 do not overlap longitudinally. Theinner staples 3242a are separated from themiddle staples 3242b by a longitudinal gap X_A/B , and theouter staples 3242c are separated from themiddle staples 3242b by a longitudinal gap X_B/C . The longitudinal gap X_A/B between theinner staples 3242a and themiddle staples 3242b is less than the longitudinal gap X_B/C between theouter staples 3242c and themiddle staples 3242b . In other examples, the longitudinal gap X_A/B may be greater than or equal to the longitudinal gap X_B/C . In certain examples, themiddle staples 3242b can longitudinally overlap theinner staples 3242a and/or theouter staples 3242c.

由图27中的钉腔的布置产生的侧向重叠和纵向间隙可足以充分阻挡穿过钉线的流体通路以密封组织。在各种实例中，侧向和/或纵向重叠和/或间隙可被构造成能够选择性地优化钉线的密封特性。除此之外或另选地，侧向和/或纵向重叠和/或间隙可被构造成能够选择性地优化钉线的柔性。此外，可使重叠最小化。在某些实例中，侧向重叠可小于钉长度的三分之一，并且在至少一个实例中可约等于钉的直径。The lateral overlap and longitudinal gap created by the arrangement of the staple cavities in Figure 27 may be sufficient to sufficiently block fluid passage through the staple line to seal the tissue. In various examples, the lateral and/or longitudinal overlaps and/or gaps can be configured to selectively optimize the sealing properties of the staple line. Additionally or alternatively, the lateral and/or longitudinal overlaps and/or gaps may be configured to selectively optimize the flexibility of the staple line. Furthermore, overlap can be minimized. In certain instances, the lateral overlap can be less than one-third of the length of the staples, and in at least one instance can be approximately equal to the diameter of the staples.

现在参见图28，示出了钉仓体3300的一部分。钉仓体3300包括平台3302和纵向狭槽3304。纵向狭槽3304沿纵向轴线LA延伸。钉腔3310 限定在钉仓体3300中，并且每个钉腔3310包括平台3302中的开口3312。钉3342被定位在每个钉腔3310中。钉3342在许多方面可类似于钉3042 (图10)或钉3142(图11)。在某些实例中，每个钉3342的腿部可偏置抵靠钉腔3310的内壁。读者将理解，钉腔3310中的钉3342的布置对应于当钉3342从钉仓体3300被击发并进入组织时钉3342在钉线中的布置。更具体地，所得到的钉线中的每个钉3342的基部与腔轴线CA共线或基本上共线。Referring now to FIG. 28, a portion of thestaple cartridge body 3300 is shown. Thecartridge body 3300 includes aplatform 3302 and alongitudinal slot 3304. Thelongitudinal slot 3304 extends along the longitudinal axis LA.Staple cavities 3310 are defined in thestaple cartridge body 3300 , and eachstaple cavity 3310 includes anopening 3312 in theplatform 3302 . Astaple 3342 is positioned in eachstaple cavity 3310.Staples 3342 may be similar in many respects to staples 3042 (FIG. 10) or staples 3142 (FIG. 11). In some examples, the legs of each staple 3342 can be biased against the inner wall of thestaple cavity 3310. The reader will understand that the placement of thestaples 3342 in thestaple cavity 3310 corresponds to the placement of thestaples 3342 in the staple line when thestaples 3342 are fired from thestaple cartridge body 3300 and into tissue. More specifically, the base of each staple 3342 in the resulting staple line is collinear or substantially collinear with the lumen axis CA.

钉腔开口3312在纵向狭槽3304的第一侧上被布置成三个排3314a， 3314b和3314c。内开口3312a限定内排3314a中的内腔3310a的周边，中间开口3312b限定中间排3314b中的中间腔3310b的周边，并且外开口 3312c限定外排3314c中的外腔3310c的周边。内部钉3342a被定位在内腔3310a中，中间钉3342b被定位在中间腔3310b中，并且外部钉3342c 被定位在外腔3310c中。尽管未在图28中示出，在至少一个实例中，狭槽3304的相对侧上的钉腔3310形成纵向狭槽3304的第一侧上的钉腔 3310的镜像反射。因此，在所得到的钉线中的钉3342的布置相对于切割线对称。在其他实例中，钉线可相对于切割线不对称。Thestaple cavity openings 3312 are arranged in threerows 3314a, 3314b and 3314c on the first side of thelongitudinal slot 3304. Theinner opening 3312a defines the perimeter of theinner cavity 3310a in theinner row 3314a, themiddle opening 3312b defines the perimeter of themiddle cavity 3310b in themiddle row 3314b, and theouter opening 3312c defines the perimeter of theouter cavity 3310c in theouter row 3314c.Inner staples 3342a are positioned ininner lumen 3310a,middle staples 3342b are positioned inmiddle lumen 3310b, and outer staples 3342c are positioned inouter lumen 3310c. Although not shown in FIG. 28 , in at least one example, thestaple cavities 3310 on opposite sides of theslot 3304 form a mirror image of thestaple cavities 3310 on the first side of thelongitudinal slot 3304. Thus, the arrangement ofstaples 3342 in the resulting staple line is symmetrical relative to the cut line. In other examples, the staple line may be asymmetric relative to the cut line.

每个钉腔开口3312具有第一端部或近侧端部3316和第二端部或远侧端部3318。腔轴线CA在每个开口3312的近侧端部3316和远侧端部 3318之间延伸。每个相应排中的钉腔开口3312是平行的。例如，内腔 3310a相对于纵向轴线LA以角度A取向。换句话说，内开口3312a的腔轴线(例如，CA_A)相对于纵向轴线LA以角度A取向。中间腔3310b 相对于纵向轴线LA以角度B取向。换句话说，中间开口3312b的腔轴线(例如，CA_B)相对于纵向轴线LA以角度B取向。外腔3310c相对于纵向轴线LA以角度C取向。换句话说，由外开口3312c限定的腔轴线(例如，CA_C)相对于纵向轴线LA以角度C取向。Eachstaple cavity opening 3312 has a first orproximal end 3316 and a second ordistal end 3318. The lumen axis CA extends between theproximal end 3316 and thedistal end 3318 of eachopening 3312. Thestaple cavity openings 3312 in each respective row are parallel. For example,lumen 3310a is oriented at angle A relative to longitudinal axis LA. In other words, the lumen axis (eg, CA_A ) of theinner opening 3312a is oriented at an angle A relative to the longitudinal axis LA. Theintermediate cavity 3310b is oriented at an angle B relative to the longitudinal axis LA. In other words, the lumen axis (eg, CA_B ) of theintermediate opening 3312b is oriented at an angle B relative to the longitudinal axis LA. Theouter lumen 3310c is oriented at an angle C relative to the longitudinal axis LA. In other words, the lumen axis (eg, CA_C ) defined by theouter opening 3312c is oriented at an angle C relative to the longitudinal axis LA.

在钉仓体3300中，角度A等于角度C，并且角度B是角度A和C 的补角。因此，内开口3312a平行于外开口3312c，并且中间开口3312b 分别垂直于内开口3312a和外开口3312c。钉仓体3300中的钉腔开口3312 形成人字形图案。此外，仍然参见图28，每个排3314a，3314b，3314c 中的钉3342具有相同长度的基部BL。钉排的宽度相等，并且钉3342的纵向长度也相等。Incartridge body 3300, angle A is equal to angle C, and angle B is the supplement of angles A and C. Thus, theinner opening 3312a is parallel to theouter opening 3312c, and themiddle opening 3312b is perpendicular to theinner opening 3312a and theouter opening 3312c, respectively. Thestaple cavity openings 3312 in thestaple cartridge body 3300 form a herringbone pattern. Furthermore, still referring to Figure 28, thestaples 3342 in eachrow 3314a, 3314b, 3314c have the same length of base BL. The rows of staples are of equal width and the longitudinal lengths ofstaples 3342 are also equal.

仍然参见图28，内部钉3342a和中间钉3342b之间的纵向重叠X_A/B等于外部钉3342c和中间钉3342b之间的纵向重叠X_B/C。此外，内部钉 3342a和中间钉3342b之间的侧向重叠Y_A/B等于外部钉3342c和中间钉 3342b之间的侧向重叠Y_B/C。在所述实例中，中间钉3342b等距离地靠近内部钉3342a和外部钉3342c定位。Still referring to Figure 28, the longitudinal overlap X_A/B between theinner staples 3342a and themiddle staples 3342b is equal to the longitudinal overlap X_B/C between the outer staples 3342c and themiddle staples 3342b. Furthermore, the lateral overlap Y_A/B between theinner staples 3342a and themiddle staples 3342b is equal to the lateral overlap Y_B/C between the outer staples 3342c and themiddle staples 3342b . In the example, themiddle staples 3342b are positioned equidistantly adjacent to theinner staples 3342a and outer staples 3342c.

仍然参见图28，使仓体3300中的钉腔3310之间的间距最小化。例如，钉腔开口3312的近侧端部3316和远侧端部3318定位成邻近其他钉腔3312。在某些实例中，相邻的钉腔可邻接接触。通过最小化钉腔3310 之间的间距，钉腔3310的密度和图28的布置中的钉腔3310之间的重叠程度被最大化。尽管重叠程度最大化，但由于钉腔的紧密接近，侧向重叠仍然小于钉长度的三分之一。Still referring to FIG. 28, the spacing betweenstaple cavities 3310 in thecartridge body 3300 is minimized. For example, proximal ends 3316 anddistal ends 3318 ofstaple cavity openings 3312 are positioned adjacent toother staple cavities 3312. In certain instances, adjacent staple cavities may be in abutting contact. By minimizing the spacing between thestaple cavities 3310, the density of thestaple cavities 3310 and the degree of overlap between thestaple cavities 3310 in the arrangement of FIG. 28 are maximized. Although the overlap is maximized, the lateral overlap is still less than one-third of the staple length due to the close proximity of the staple cavities.

在其他实例中，至少一个钉腔排中的钉腔的角度取向可与其他排中的钉腔的角度取向不同。除此之外或另选地，至少一个钉腔排中的钉基部的长度可与至少另一个排中的钉基部的长度不同。除此之外或另选地，钉腔可不与每个相邻排中的相邻钉腔等距交错或偏置。钉仓和其中的钉的这种变化可相对于切割线产生侧向地具有不同特性的钉线。In other examples, the angular orientation of the staple cavities in at least one row of staple cavities may be different from the angular orientation of the staple cavities in other rows. Additionally or alternatively, the staple bases in at least one row of staple cavities may have a different length than the staple bases in at least another row. Additionally or alternatively, the staple cavities may not be equidistantly staggered or offset from adjacent staple cavities in each adjacent row. This variation of the staple cartridge and the staples therein can result in staple lines having different properties laterally relative to the cutting line.

在某些实例中，例如，钉线的内部部分中的钉(诸如从钉腔的内排击发的钉)可具有与钉线的外部部分中的钉不同的基部长度。例如，刀狭槽的每个侧面上的钉腔的内排中的钉可具有比钉腔的其他排中的钉更长的基部。较长的基部可提供更大的密封能力，因为例如钉可捕获更多的组织。除此之外或另选地，较长的基部可增强钉线并降低其柔性。In certain instances, for example, the staples in the inner portion of the staple line (such as staples fired from the inner row of staple cavities) may have a different base length than the staples in the outer portion of the staple line. For example, staples in an inner row of staple cavities on each side of the knife slot may have longer bases than staples in other rows of staple cavities. A longer base can provide greater sealing capability because, for example, the staples can capture more tissue. Additionally or alternatively, a longer base can strengthen the staple line and reduce its flexibility.

现在参见图29，示出了钉仓体3400的一部分。钉仓体3400包括平台3402和纵向狭槽3404。纵向狭槽3404沿纵向轴线LA延伸。钉腔3410 限定在钉仓体3400中，并且每个钉腔3410在平台3402中限定开口3412。钉3442被定位在每个钉腔3410中。钉3442在许多方面可类似于钉3042 (图10)或钉3142(图11)。在某些实例中，每个钉3442的腿部可偏置抵靠钉腔3410的内壁。读者将理解，钉腔3410中的钉3442的布置对应于当钉3442从仓体3400被击发并进入组织时钉3442在钉线中的布置。更具体地，所得到的钉线中的每个钉3442的基部与腔轴线CA共线或基本上共线。Referring now to FIG. 29, a portion of thestaple cartridge body 3400 is shown. Thecartridge body 3400 includes aplatform 3402 and alongitudinal slot 3404. Thelongitudinal slot 3404 extends along the longitudinal axis LA.Staple cavities 3410 are defined in thestaple cartridge body 3400 , and eachstaple cavity 3410 defines anopening 3412 in theplatform 3402 . Astaple 3442 is positioned in eachstaple cavity 3410.Staples 3442 may be similar in many respects to staples 3042 (FIG. 10) or staples 3142 (FIG. 11). In some examples, the legs of each staple 3442 can be biased against the inner wall of thestaple cavity 3410 . The reader will understand that the placement of thestaples 3442 in thestaple cavity 3410 corresponds to the placement of thestaples 3442 in the staple line when thestaples 3442 are fired from thecartridge body 3400 and into tissue. More specifically, the base of each staple 3442 in the resulting staple line is collinear or substantially collinear with the lumen axis CA.

钉腔开口3412在纵向狭槽3404的第一侧上被布置成三个排3414a， 3414b和3414c。内开口3412a限定内排3414a中的内腔3410a的周边，中间开口3412b限定中间排3414b中的中间腔3410b的周边，并且外开口 3412c限定外排3414c中的外腔3410c的周边。内部钉3442a被定位在内腔3410a中，中间钉3442b被定位在中间腔3410b中，并且外部钉3442c 被定位在外腔3410c中。尽管未在图29中示出，在至少一个实例中，狭槽3404的相对侧上的钉腔3410形成纵向狭槽3404的第一侧上的钉腔 3410的镜像反射。因此，在所得到的钉线中的钉3442的布置相对于切割线对称。在其他实例中，钉线可相对于切割线不对称。Thestaple cavity openings 3412 are arranged on a first side of thelongitudinal slot 3404 in threerows 3414a, 3414b and 3414c. Theinner opening 3412a defines the perimeter of the inner cavity 3410a in theinner row 3414a, themiddle opening 3412b defines the perimeter of themiddle cavity 3410b in themiddle row 3414b, and theouter opening 3412c defines the perimeter of the outer cavity 3410c in theouter row 3414c.Inner staples 3442a are positioned in inner lumen 3410a,middle staples 3442b are positioned inmiddle lumen 3410b, andouter staples 3442c are positioned in outer lumen 3410c. Although not shown in FIG. 29 , in at least one example, thestaple cavities 3410 on opposite sides of theslot 3404 form a mirror image of thestaple cavities 3410 on the first side of thelongitudinal slot 3404. Thus, the arrangement ofstaples 3442 in the resulting staple line is symmetrical relative to the cut line. In other examples, the staple line may be asymmetric relative to the cut line.

每个钉腔开口3412具有第一端部或近侧端部3416和第二端部或远侧端部3418。腔轴线CA在每个开口3412的近侧端部3416和远侧端部 3418之间延伸。每个排中的钉腔开口3412是平行的。例如，内腔3410a 相对于纵向轴线LA以角度A取向。换句话说，内开口3412a的腔轴线 (例如，CA_A)相对于纵向轴线LA以角度A取向。中间腔3410b相对于纵向轴线LA以角度B取向。换句话说，中间开口3412b的腔轴线(例如，CA_B)相对于纵向轴线LA以角度B取向。外腔3410c相对于纵向轴线LA以角度C取向。换句话说，由外开口3412c限定的腔轴线(例如， CA_C)相对于纵向轴线LA以角度C取向。Eachstaple cavity opening 3412 has a first orproximal end 3416 and a second ordistal end 3418. The lumen axis CA extends between theproximal end 3416 and thedistal end 3418 of eachopening 3412. Thestaple cavity openings 3412 in each row are parallel. For example, lumen 3410a is oriented at angle A relative to longitudinal axis LA. In other words, the lumen axis (eg, CA_A ) of theinner opening 3412a is oriented at an angle A relative to the longitudinal axis LA.Intermediate cavity 3410b is oriented at angle B relative to longitudinal axis LA. In other words, the lumen axis (eg, CA_B ) of theintermediate opening 3412b is oriented at an angle B relative to the longitudinal axis LA. The outer lumen 3410c is oriented at an angle C relative to the longitudinal axis LA. In other words, the lumen axis (eg, CA_C ) defined by theouter opening 3412c is oriented at an angle C relative to the longitudinal axis LA.

角度A、B和C是不同的。内开口3412a相对于外开口3412c倾斜地取向。角度A小于角度C。因为外开口3412c的轴线(例如，轴线CA_C) 不平行于内开口3412a的轴线(例如，轴线CA_A)，所以钉仓体3400中的钉腔开口3412形成修改的或倾斜的人字形图案。中间开口3412b的腔轴线CA_B可取向成垂直于或基本上垂直于内开口3412a或外开口3412c。例如，角度B可以是角度A或C的补角。在其他实例中，角度B可不是角度A或C的补角。Angles A, B and C are different. Theinner opening 3412a is oriented obliquely relative to theouter opening 3412c. Angle A is less than angle C. Because the axis ofouter opening 3412c (eg, axis CA_C ) is not parallel to the axis ofinner opening 3412a (eg, axis CA_A ),staple cavity openings 3412 incartridge body 3400 form a modified or angled chevron pattern. The lumen axis CA_B of theintermediate opening 3412b may be oriented perpendicular or substantially perpendicular to theinner opening 3412a or theouter opening 3412c. For example, angle B may be the supplement of angle A or C. In other examples, angle B may not be the supplement of angles A or C.

仍然参见图29，内部钉3442a具有基部长度BL_A，中间钉3442b具有基部长度BL_B，并且外部钉3442c具有基部长度BL_C。基部长度BL_A大于基部长度BL_B和基部长度BL_C。换句话说，内部钉3442a比中间钉3442b 和外部钉3442c长。此外，容纳内部钉3442a的钉腔3410相应地更大以容纳更长的基部BL_A。Still referring to Fig. 29,inner staple 3442a has a base length BL_A ,middle staple 3442b has a base length BL_B , and outer staple 3442c has a base length BL_C ._The base length BLA is greater than the base length_BLB and the base length_BLC . In other words, theinner staples 3442a are longer than themiddle staples 3442b andouter staples 3442c. Additionally, thestaple cavity 3410 that accommodates the inner staples_3442a is correspondingly larger to accommodate the longer base BLA.

钉仓3400中的钉腔3410的布置在中间钉3442b的近侧端部和远侧端部处提供内部钉3442a和中间钉3442b之间的纵向重叠X_A/B。中间钉3442b 在两个相邻的内部钉3442a之间等距间隔并纵向交错。中间钉3442b也在两个相邻的外部钉3442c之间等距间隔并纵向交错。每个外部钉3442c 的近侧端部与中间钉3442b的远侧端部纵向对准，并且每个外部钉3442c 的远侧端部与另一个中间钉3442b的近侧端部纵向对准。换句话说，这种钉纵向对准，并且纵向重叠等于钉3442的直径。钉仓3400中的钉腔 3410的布置还在内排3414a和中间排3414b之间提供侧向间隙Y_A/B，并且在外排3414c和中间排3414b之间提供侧向重叠Y_B/C。在所述实例中，中间钉3442b定位成更靠近外部钉3442c而不是内部钉3442a。The arrangement of thestaple cavities 3410 in thestaple cartridge 3400 provides longitudinal overlap X_A/B between theinner staples 3442a and theintermediate staples 3442b at the proximal and distal ends of theintermediate staples 3442b.Intermediate staples 3442b are equally spaced and longitudinally staggered between two adjacentinner staples 3442a.Intermediate staples 3442b are also equally spaced and longitudinally staggered between two adjacentouter staples 3442c. The proximal end of eachouter staple 3442c is longitudinally aligned with the distal end of theintermediate staple 3442b, and the distal end of eachouter staple 3442c is longitudinally aligned with the proximal end of the otherintermediate staple 3442b. In other words, the staples are aligned longitudinally and the longitudinal overlap is equal to the diameter of thestaples 3442. The arrangement ofstaple cavities 3410 instaple cartridge 3400 also provides lateral clearance Y_A/B betweeninner row 3414a andmiddle row 3414b , and lateral overlap Y_B/C betweenouter row 3414c andmiddle row 3414b . In the example, themiddle staples 3442b are positioned closer to theouter staples 3442c than theinner staples 3442a.

仍然参见图29，由钉仓体3400产生的钉线可相对于切割线侧向地具有不同的特性。具体地，相比于从切割线侧向向外，钉线沿切割线可具有更大的密封效果。此外，相比于向内朝向切割线，钉线侧向远离切割线可具有更大的柔性。例如，因为内部钉3442a的基部BL_A分别比中间钉3442b和外部钉3442c的基部BL_B和BL_C长，所以钉线的内部部分相比于钉线的外部部分可具有更大的密封效果和/或更小的柔性。除此之外或另选地，因为内部钉3442a以小于外部钉3442c的角度取向并且比外部钉 3442c更接近平行取向，所以钉线的内部部分相比于钉线的外部部分可具有更大的密封效果和/或更小的柔性。除此之外或另选地，因为中间钉 3442b与内部钉3442a纵向重叠但不与外部钉3442c纵向重叠，所以钉线的内部部分相比于钉线的外部部分可具有更大的密封效果和/或更小的柔性。可最小化重叠量。例如，重叠可小于钉长度的三分之一，并且在至少一个实例中可约等于钉的直径。Still referring to Fig. 29, the staple lines produced by thestaple cartridge body 3400 can have different properties laterally relative to the cutting line. Specifically, the staple line may have a greater sealing effect along the cut line than laterally outward from the cut line. Furthermore, the staple line may have greater flexibility laterally away from the cut line than inward toward the cut line. For example, because the bases BL_A of theinner staples 3442a are longer than the bases BL_B and BL_C of the middle andouter staples 3442b and 3442c, respectively, the inner portion of the staple line may have a greater sealing effect and better sealing effect than the outer portion of the staple line. / or less flexible. Additionally or alternatively, because theinner staples 3442a are oriented at a smaller angle than theouter staples 3442c and are oriented more nearly parallel than theouter staples 3442c, the inner portion of the staple line may have a larger size than the outer portion of the staple line sealing effect and/or less flexibility. Additionally or alternatively, because theintermediate staples 3442b longitudinally overlap theinner staples 3442a but not theouter staples 3442c, the inner portion of the staple line may have a greater sealing effect and / or less flexible. The amount of overlap can be minimized. For example, the overlap can be less than one-third the length of the staple, and in at least one instance can be approximately equal to the diameter of the staple.

在某些实例中，例如，钉线的外部部分中的钉(诸如从钉腔的外排击发的钉)可具有与钉线的内部部分中的钉不同的基部长度。例如，刀狭槽的每个侧面上的钉腔的外排中的钉可具有比钉腔的其他排中的钉更短的基部。例如，较短的基部可提供钉线的增加的柔性。In certain instances, for example, the staples in the outer portion of the staple line (such as staples fired from the outer row of the staple cavity) may have a different base length than the staples in the inner portion of the staple line. For example, staples in the outer row of staple cavities on each side of the knife slot may have shorter bases than staples in other rows of staple cavities. For example, a shorter base may provide increased flexibility of the staple line.

现在参见图30，示出了钉仓体3500的一部分。钉仓体3500包括平台3502和纵向狭槽3504。纵向狭槽3504沿纵向轴线LA延伸。钉腔3510 限定在钉仓体3500中，并且每个钉腔3510在平台3502中限定开口3512。钉3542被定位在每个钉腔3510中。钉3542在许多方面可类似于钉3042 (图10)或钉3142(图11)。在某些实例中，每个钉3542的腿部可偏置抵靠钉腔3510的内壁。读者将理解，钉腔3510中的钉3542的布置对应于当钉3542从仓体3500被击发并进入组织时钉3542在钉线中的布置。更具体地，所得到的钉线中的每个钉3542的基部与腔轴线CA共线或基本上共线。Referring now to FIG. 30, a portion of astaple cartridge body 3500 is shown. Thecartridge body 3500 includes aplatform 3502 and alongitudinal slot 3504. Thelongitudinal slot 3504 extends along the longitudinal axis LA.Staple cavities 3510 are defined in thestaple cartridge body 3500 , and eachstaple cavity 3510 defines anopening 3512 in theplatform 3502 . A staple 3542 is positioned in eachstaple cavity 3510. Staples 3542 may be similar in many respects to staples 3042 (FIG. 10) or staples 3142 (FIG. 11). In some instances, the legs of each staple 3542 can be biased against the inner wall of thestaple cavity 3510. The reader will understand that the placement of the staples 3542 in thestaple cavity 3510 corresponds to the placement of the staples 3542 in the staple line when the staples 3542 are fired from thecartridge body 3500 and into tissue. More specifically, the base of each staple 3542 in the resulting staple line is collinear or substantially collinear with the lumen axis CA.

钉腔开口3512在纵向狭槽3504的第一侧上被布置成三个排3514a， 3514b和3514c。内开口3512a限定内排3514a中的内腔3510a的周边，中间开口3512b限定中间排3514b中的中间腔3510b的周边，并且外开口 3512c限定外排3514c中的外腔3510c的周边。内部钉3542a被定位在内腔3510a中，中间钉3542b被定位在中间腔3510b中，并且外部钉3542c 被定位在外腔3510c中。尽管未在图30中示出，在至少一个实例中，狭槽3504的相对侧上的钉腔3510形成纵向狭槽3504的第一侧上的钉腔 3510的镜像反射。因此，在所得到的钉线中的钉3542的布置相对于切割线对称。在其他实例中，钉线可相对于切割线不对称。Thestaple cavity openings 3512 are arranged in threerows 3514a, 3514b and 3514c on the first side of thelongitudinal slot 3504. The inner opening 3512a defines the perimeter of theinner cavity 3510a in theinner row 3514a, themiddle opening 3512b defines the perimeter of themiddle cavity 3510b in themiddle row 3514b, and theouter opening 3512c defines the perimeter of theouter cavity 3510c in theouter row 3514c.Inner staples 3542a are positioned ininner lumen 3510a,middle staples 3542b are positioned inmiddle lumen 3510b, andouter staples 3542c are positioned inouter lumen 3510c. Although not shown in FIG. 30 , in at least one example, thestaple cavities 3510 on opposite sides of theslot 3504 form a mirror image of thestaple cavities 3510 on the first side of thelongitudinal slot 3504. Thus, the arrangement of staples 3542 in the resulting staple line is symmetrical relative to the cut line. In other examples, the staple line may be asymmetric relative to the cut line.

每个钉腔开口3512具有第一端部或近侧端部3516和第二端部或远侧端部3518。腔轴线CA在每个开口3512的近侧端部3516和远侧端部 3518之间延伸。每个排中的钉腔开口3512是平行的。例如，内腔3510a 相对于纵向轴线LA以角度A取向。换句话说，内开口3512a的腔轴线 (例如，CA_A)相对于纵向轴线LA以角度A取向。中间腔3510b相对于纵向轴线LA以角度B取向。换句话说，中间开口3512b的腔轴线(例如，CA_B)相对于纵向轴线LA以角度B取向。外腔3510c相对于纵向轴线LA以角度C取向。换句话说，由外开口3512c限定的腔轴线(例如， CA_C)相对于纵向轴线LA以角度C取向。Eachstaple cavity opening 3512 has a first orproximal end 3516 and a second ordistal end 3518. The lumen axis CA extends between theproximal end 3516 and thedistal end 3518 of eachopening 3512. Thestaple cavity openings 3512 in each row are parallel. For example,lumen 3510a is oriented at angle A relative to longitudinal axis LA. In other words, the lumen axis (eg, CA_A ) of the inner opening 3512a is oriented at an angle A relative to the longitudinal axis LA.Intermediate cavity 3510b is oriented at angle B relative to longitudinal axis LA. In other words, the lumen axis (eg, CA_B ) of theintermediate opening 3512b is oriented at an angle B relative to the longitudinal axis LA. Theouter lumen 3510c is oriented at an angle C relative to the longitudinal axis LA. In other words, the lumen axis (eg, CA_C ) defined by theouter opening 3512c is oriented at an angle C relative to the longitudinal axis LA.

角度A、B和C可不同。内开口3512a相对于外开口3512c倾斜地取向。角度A小于角度C。因为外开口3512c的轴线(例如，轴线CA_C) 不平行于内开口3512a的轴线(例如，轴线CA_A)，所以钉仓体3500中的钉腔开口3512形成修改的或倾斜的人字形图案。中间开口3512b的腔轴线CA_B可取向成垂直于或基本上垂直于内开口3512a或外开口3512c。例如，角度B可以是角度A或C的补角。在其他实例中，角度B可不是角度A或C的补角。Angles A, B and C can be different. The inner opening 3512a is oriented obliquely relative to theouter opening 3512c. Angle A is less than angle C. Because the axis ofouter opening 3512c (eg, axis CA_C ) is not parallel to the axis of inner opening 3512a (eg, axis CA_A ),staple cavity openings 3512 incartridge body 3500 form a modified or angled chevron pattern. The lumen axis CA_B of theintermediate opening 3512b may be oriented perpendicular or substantially perpendicular to the inner opening 3512a or theouter opening 3512c. For example, angle B may be the supplement of angle A or C. In other examples, angle B may not be the supplement of angles A or C.

内部钉3542a具有基部长度BL_A，中间钉3542b具有基部长度BL_B，并且外部钉3542c具有基部长度BL_C。基部长度BL_C小于基部长度BL_B和基部长度BL_A。换句话说，外部钉3542c比中间钉3542b和内部钉3542a 短。此外，容纳外部钉3542c的钉腔3510相应地较短以容纳较短的基部 BL_C。Inner staple 3542a has a base length BL_A ,middle staple 3542b has a base length BL_B , and outer staple 3542c has a base length BL_C . The base length BL_C is smaller than the base length BL_B and the base length BL_A . In other words,outer staples 3542c are shorter thanintermediate staples 3542b andinner staples 3542a. Additionally, thestaple cavity 3510 that accommodates the outer staples_3542c is correspondingly shorter to accommodate the shorter base BLC.

钉仓3500中的钉腔3510的布置在中间钉3542b的近侧端部和远侧端部处提供内部钉3542a和中间钉3542b之间的纵向重叠X_A/B。中间钉3542b 在两个相邻的内部钉3542a之间等距间隔并纵向交错。钉仓3500中的钉腔3510的布置还在中间钉3542b的近侧端部和远侧端部处提供中间钉 3542b和外部钉3542c之间的纵向重叠X_B/C。中间钉3542b也在两个相邻的外部钉3542c之间等距间隔并纵向交错。由于钉3542的角度取向和间距，纵向重叠X_A/B大于纵向重叠X_B/C。钉仓3500中的钉腔3510的布置还在内部钉3542a和中间钉3542b之间提供侧向间隙Y_A/B，并且在外部钉 3542c和中间钉3542b之间提供侧向重叠Y_B/C。在所述实例中，中间钉 3542b定位成相比于内部钉3542a更靠近外部钉3542c。The arrangement of thestaple cavities 3510 in thestaple cartridge 3500 provides longitudinal overlap X_A/B between theinner staples 3542a and theintermediate staples 3542b at the proximal and distal ends of theintermediate staples 3542b.Intermediate staples 3542b are equally spaced and longitudinally staggered between two adjacentinner staples 3542a. The arrangement of thestaple cavities 3510 in thestaple cartridge 3500 also provides longitudinal overlap X_B/C between theintermediate staples 3542b and theouter staples 3542c at the proximal and distal ends of theintermediate staples 3542b.Intermediate staples 3542b are also equally spaced and longitudinally staggered between two adjacentouter staples 3542c. Due to the angular orientation and spacing of the staples 3542, the longitudinal overlap X_A/B is greater than the longitudinal overlap X_B/C . The arrangement ofstaple cavities 3510 instaple cartridge 3500 also provides lateral clearance Y_A/B betweeninner staples 3542a andintermediate staples 3542b , and lateral overlap Y_B/C betweenouter staples 3542c andintermediate staples 3542b . In the example, themiddle staples 3542b are positioned closer to theouter staples 3542c than theinner staples 3542a.

仍然参见图30，由钉仓体3500产生的钉线可相对于切割线侧向地具有不同的特性。具体地，相比于从切割线侧向向外，钉线沿切割线可具有更大的密封效果。此外，相比于向内朝向切割线，钉线侧向远离切割线可具有更大的柔性。例如，因为外部钉3542c的基部BL_C分别比中间钉3542b和外部钉3542c的基部BL_A和BL_B短，所以钉线的内部部分相比于钉线的外部部分可具有更大的密封效果和/或更小的柔性。除此之外或另选地，因为内部钉3542a以小于外部钉3542c的角度取向并且比外部钉 3542c更接近平行取向，所以钉线的内部部分相比于钉线的外部部分可具有更大的密封效果和/或更小的柔性。除此之外或另选地，因为相比于中间钉3542b纵向地重叠外部钉3542c，中间钉3542b更加纵向地重叠内部钉3542a，所以钉线的内部部分可具有比钉线的外部部分更大的密封效果和/或更小的柔性。Still referring to Fig. 30, the staple lines produced by thestaple cartridge body 3500 can have different properties laterally relative to the cutting line. Specifically, the staple line may have a greater sealing effect along the cut line than laterally outward from the cut line. Furthermore, the staple line may have greater flexibility laterally away from the cut line than inward toward the cut line. For example, because the bases BL_C of theouter staples 3542c are shorter than the bases BL_A and BL_B of the middle andouter staples 3542b and 3542c, respectively, the inner portion of the staple line may have a greater sealing effect and a greater sealing effect than the outer portion of the staple line. / or less flexible. Additionally or alternatively, because theinner staples 3542a are oriented at a smaller angle than theouter staples 3542c and are oriented more nearly parallel than theouter staples 3542c, the inner portion of the staple line can have a larger size than the outer portion of the staple line sealing effect and/or less flexibility. Additionally or alternatively, since themiddle staples 3542b overlap theinner staples 3542a more longitudinally than themiddle staples 3542b longitudinally overlap theouter staples 3542c, the inner portion of the staple line may have a larger size than the outer portion of the staple line sealing effect and/or less flexibility.

在各种实例中，可在每个钉排中定制钉线的特性。在刀狭槽的一侧上的每个钉腔排中的钉可具有不同的基部长度。另外，刀狭槽的一侧上的每个钉腔排中的钉可相对于刀狭槽以不同的角度取向。此外，腔之间的间距可逐排变化。例如，可选择每个排中的钉的尺寸和取向，以基于从切割线朝向钉线的外边界侧向的排的位置来优化钉线的柔性和每个排中的密封特性。在某些实例中，例如，沿切割线可最大化或强调密封效果，并且例如，可沿钉线的外边界最大化或强调钉线的柔性。另选地，在某些实例中，可沿钉线的外边界最大化或强调密封效果和/或可沿切割线最大化或强调钉线的柔性。In various instances, the characteristics of the staple lines in each staple row can be customized. The staples in each staple cavity row on one side of the knife slot can have different base lengths. Additionally, the staples in each staple cavity row on one side of the knife slot may be oriented at different angles relative to the knife slot. Furthermore, the spacing between the cavities can vary from row to row. For example, the size and orientation of the staples in each row can be selected to optimize the flexibility of the staple line and the sealing properties in each row based on the position of the row lateral to the outer boundary of the staple line from the cut line. In some instances, the sealing effect may be maximized or emphasized along the cut line, for example, and the flexibility of the staple line may be maximized or emphasized, for example, along the outer boundary of the staple line. Alternatively, in some instances, the sealing effect may be maximized or emphasized along the outer boundary of the staple line and/or the flexibility of the staple line may be maximized or emphasized along the cut line.

现在参见图31，示出了钉仓体3600的一部分。钉仓体3600包括平台3602和纵向狭槽3604。纵向狭槽3604沿纵向轴线LA延伸。钉腔3610 限定在钉仓体3600中，并且每个钉腔3610在平台3602中限定开口3612。钉3642被定位在每个钉腔3610中。钉3642在许多方面可类似于钉3042 (图10)或钉3142(图11)。在某些实例中，每个钉3642的腿部可偏置抵靠钉腔3610的内壁。读者将理解，钉腔3610中的钉3642的布置对应于当钉3642从仓体3600被击发并进入组织时钉3642在钉线中的布置。更具体地，所得到的钉线中的每个钉3642的基部与腔轴线CA共线或基本上共线。Referring now to FIG. 31, a portion of astaple cartridge body 3600 is shown.Cartridge body 3600 includesplatform 3602 andlongitudinal slot 3604. Thelongitudinal slot 3604 extends along the longitudinal axis LA.Staple cavities 3610 are defined in thestaple cartridge body 3600 , and eachstaple cavity 3610 defines anopening 3612 in theplatform 3602 . A staple 3642 is positioned in eachstaple cavity 3610. Staples 3642 may be similar in many respects to staples 3042 (FIG. 10) or staples 3142 (FIG. 11). In some examples, the legs of each staple 3642 can be biased against the inner wall of thestaple cavity 3610. The reader will understand that the placement of the staples 3642 in thestaple cavity 3610 corresponds to the placement of the staples 3642 in the staple line when the staples 3642 are fired from thecartridge body 3600 and into tissue. More specifically, the base of each staple 3642 in the resulting staple line is collinear or substantially collinear with the lumen axis CA.

钉腔开口3612在纵向狭槽3604的第一侧上被布置成三个排3614a， 3614b，3614c。内开口3612a限定内排3614a中的内腔3610a的周边，中间开口3612b限定中间排3614b中的中间腔3610b的周边，并且外开口3612c限定外排3614c中的外腔3610c的周边。内部钉3642a被定位在内腔3610a中，中间钉3642b被定位在中间腔3610b中，并且外部钉3642c 被定位在外腔3610c中。尽管未在图31中示出，在至少一个实例中，狭槽3604的相对侧上的钉腔3610形成纵向狭槽3604的第一侧上的钉腔3610的镜像反射。因此，在所得到的钉线中的钉3642的布置相对于切割线对称。在其他实例中，钉线可相对于切割线不对称。Thestaple cavity openings 3612 are arranged in threerows 3614a, 3614b, 3614c on the first side of thelongitudinal slot 3604.Inner opening 3612a defines the perimeter ofinner cavity 3610a ininner row 3614a, middle opening 3612b defines the perimeter ofmiddle cavity 3610b inmiddle row 3614b, andouter opening 3612c defines the perimeter of outer cavity 3610c inouter row 3614c.Inner staples 3642a are positioned ininner lumen 3610a,middle staples 3642b are positioned inmiddle lumen 3610b, andouter staples 3642c are positioned in outer lumen 3610c. Although not shown in FIG. 31 , in at least one example, thestaple cavities 3610 on opposite sides of theslot 3604 form a mirror image of thestaple cavities 3610 on the first side of thelongitudinal slot 3604 . Thus, the arrangement of staples 3642 in the resulting staple line is symmetrical relative to the cut line. In other examples, the staple line may be asymmetric relative to the cut line.

每个钉腔开口3612具有第一端部或近侧端部3616和第二端部或远侧端部3618。腔轴线CA在每个开口3612的近侧端部3616和远侧端部 3618之间延伸。每个排中的钉腔开口3612是平行的。例如，内腔3610a 相对于纵向轴线LA以角度A取向。换句话说，内开口3612a的腔轴线 (例如，CA_A)相对于纵向轴线LA以角度A取向。中间腔3610b相对于纵向轴线LA以角度B取向。换句话说，中间开口3612b的腔轴线(例如，CA_B)相对于纵向轴线LA以角度B取向。外腔3610c相对于纵向轴线LA以角度C取向。换句话说，由外开口3612c限定的腔轴线(例如， CA_C)相对于纵向轴线LA以角度C取向。Eachstaple cavity opening 3612 has a first orproximal end 3616 and a second ordistal end 3618. The lumen axis CA extends between theproximal end 3616 and thedistal end 3618 of eachopening 3612. Thestaple cavity openings 3612 in each row are parallel. For example,lumen 3610a is oriented at angle A relative to longitudinal axis LA. In other words, the lumen axis (eg, CA_A ) of theinner opening 3612a is oriented at an angle A relative to the longitudinal axis LA.Intermediate cavity 3610b is oriented at angle B relative to longitudinal axis LA. In other words, the lumen axis (eg, CA_B ) of the intermediate opening 3612b is oriented at an angle B relative to the longitudinal axis LA. The outer lumen 3610c is oriented at an angle C relative to the longitudinal axis LA. In other words, the lumen axis (eg, CA_C ) defined by theouter opening 3612c is oriented at an angle C relative to the longitudinal axis LA.

角度A、B和C可不同。内开口3612a相对于外开口3612c倾斜地取向。角度A小于角度C。因为外开口3612c的轴线(例如，轴线CA_C) 不平行于内开口3612a的轴线(例如，轴线CA_A)，所以钉仓体3600中的钉腔开口3612形成修改的或倾斜的人字形图案。中间开口3612b的腔轴线CA_B可取向成垂直于或基本上垂直于内开口3612a或外开口3612c。例如，角度B可以是角度A或C的补角。在其他实例中，角度B可不是角度A或C的补角。Angles A, B and C can be different. Theinner opening 3612a is oriented obliquely relative to theouter opening 3612c. Angle A is less than angle C. Because the axis ofouter opening 3612c (eg, axis CA_C ) is not parallel to the axis ofinner opening 3612a (eg, axis CA_A ),staple cavity openings 3612 incartridge body 3600 form a modified or angled chevron pattern. The lumen axis CA_B of the intermediate opening 3612b may be oriented perpendicular or substantially perpendicular to theinner opening 3612a or theouter opening 3612c. For example, angle B may be the supplement of angle A or C. In other examples, angle B may not be the supplement of angles A or C.

内部钉3642a具有基部长度BL_A，中间钉3642b具有基部长度BL_B，并且外部钉3642c具有基部长度BL_C。基部长度BL_C小于基部长度BL_B，并且基部长度BL_B小于基部长度BL_A。换句话说，钉3642的长度朝向纵向狭槽3604侧向增加。此外，钉腔3610的长度相应地朝向纵向狭槽3604 侧向增加，以容纳较大的钉。Inner staple 3642a has a base length BL_A ,middle staple 3642b has a base length BL_B , and outer staple 3642c has a base length BL_C . The base length_BLC is less than the base length_BLB , and the base length_BLB is less than the base length_BLA . In other words, the length of the staples 3642 increases laterally toward thelongitudinal slots 3604 . In addition, the length of thestaple cavity 3610 is correspondingly increased laterally toward thelongitudinal slot 3604 to accommodate larger staples.

仓体3600中的钉腔3610的布置在中间钉3642b的近侧端部和远侧端部处提供内部钉3642a和中间钉3642b之间的纵向重叠X_A/B。中间钉3642b 在两个相邻的内部钉3642a之间等距间隔并纵向交错。仓体3600中的钉腔3610的布置还在中间钉3642b的近侧端部和远侧端部处在中间钉 3642b和外部钉3642c之间提供纵向间隙X_B/C。中间钉3642b也在两个相邻的外部钉3642c之间等距间隔并纵向交错。由于钉的角度取向、钉的间距和钉的长度的变化，纵向重叠X_A/B大于纵向间隙X_B/C。在其他实例中，纵向重叠X_A/B可等于或小于纵向重叠X_B/C。仓体3600中的钉腔3610 的布置还在内排3614a和中间排3614b之间提供侧向间隙Y_A/B，并且在外排3614c和中间排3614b之间提供侧向重叠Y_B/C。The placement of thestaple cavities 3610 in thecartridge body 3600 provides longitudinal overlap X_A/B between theinner staples 3642a and theintermediate staples 3642b at the proximal and distal ends of theintermediate staples 3642b.Intermediate staples 3642b are equally spaced and longitudinally staggered between two adjacentinner staples 3642a. The arrangement of thestaple cavities 3610 in thecartridge body 3600 also provides a longitudinal gap X_B/C between theintermediate staples 3642b and theouter staples 3642c at the proximal and distal ends of theintermediate staples 3642b.Intermediate staples 3642b are also equally spaced and longitudinally staggered between two adjacentouter staples 3642c. The longitudinal overlap X_A/B is greater than the longitudinal gap X_B/C due to variations in the angular orientation of the pegs, the pitch of the pegs, and the length of the pegs. In other examples, the longitudinal overlap X_A/B may be equal to or less than the longitudinal overlap X_B/C . The arrangement of thestaple cavities 3610 in thecartridge body 3600 also provides lateral clearance Y_A/B between theinner row 3614a and themiddle row 3614b , and lateral overlap Y_B/C between theouter row 3614c and themiddle row 3614b .

仍然参见图31，由钉仓体3600产生的钉线可相对于切割线侧向地具有不同的特性。具体地，相比于从切割线侧向向外，钉线邻近切割线可具有更大的密封效果。此外，相比于向内朝向切割线，钉线侧向远离切割线可具有更大的柔性。例如，因为钉3642a，3642b和3642c的基部BL_A、 BL_B和BL_C的长度分别朝向切割线侧向向内增加，所以钉线的内部部分可具有比钉线的外部部分更大的密封效果。除此之外或另选地，因为钉 3642a，3642b和3642c的角度取向远离切割线侧向向外增加，所以钉线的外部部分可具有比钉线的内部部分更大的柔性。Still referring to Fig. 31, the staple lines produced by thestaple cartridge body 3600 can have different properties laterally relative to the cutting line. Specifically, the staple line may have a greater sealing effect adjacent the cut line than laterally outward from the cut line. Furthermore, the staple line may have greater flexibility laterally away from the cut line than inward toward the cut line. For example, because the lengths of the bases BLA, BBL, and BLC of staples_3642a ,_3642b , and_3642c , respectively, increase laterally inward toward the cut line, the inner portion of the staple line may have a greater sealing effect than the outer portion of the staple line . Additionally or alternatively, because the angular orientation ofstaples 3642a, 3642b, and 3642c increases laterally outward away from the cut line, the outer portion of the staple line may have greater flexibility than the inner portion of the staple line.

如本文所述，钉可移除地被定位在钉仓中并且在使用期间从钉仓被击发。在各种实例中，钉可从钉仓中的钉腔中被驱出并与砧座成形接触。例如，击发元件可在击发行程期间平移穿过钉仓，以将钉从钉仓朝向砧座驱动。在某些实例中，钉可被钉驱动器支撑，并且击发元件可提升钉驱动器以从钉仓射出或移除钉。As described herein, the staples are removably positioned in the staple cartridge and fired from the staple cartridge during use. In various examples, the staples may be driven from staple cavities in the staple cartridge and brought into forming contact with the anvil. For example, the firing element may translate through the staple cartridge during the firing stroke to drive the staples from the staple cartridge toward the anvil. In certain instances, the staples can be supported by the staple driver, and the firing element can lift the staple driver to eject or remove the staples from the staple cartridge.

砧座可包括钉成形表面，该钉成形表面具有限定在其中的钉成形凹坑。在某些实例中，钉成形凹坑可冲压在砧座中。例如，钉成形凹坑可压印在砧座的平坦表面中。读者将理解，钉成形凹坑的某些特征部可以是压印过程的有意后果。例如，在钉成形产品的拐角和/或边缘处的一定程度的倒圆可以是压印过程的有意结果。这些特征部还可设计成更好地将钉形成为其成形构造，包括在部署期间变得偏斜和/或以其他方式不对准的钉。The anvil can include a staple-forming surface having staple-forming pockets defined therein. In some instances, the staple forming pockets can be punched into the anvil. For example, staple forming pockets can be stamped into the flat surface of the anvil. The reader will understand that certain features of the staple forming pockets may be an intentional consequence of the embossing process. For example, a certain degree of rounding at the corners and/or edges of the staple-forming product may be an intentional result of the embossing process. These features may also be designed to better form staples into their shaped configuration, including staples that become skewed and/or otherwise misaligned during deployment.

钉仓中的每个钉可与砧座的钉成形凹坑对准。换句话说，用于端部执行器的钉仓中的钉腔和钉的布置可对应于或匹配端部执行器的砧座中的钉成形凹坑的布置。更具体地，每个钉腔的角度取向可匹配相应的钉成形凹坑的角度取向。例如，当钉腔以人字形图案布置时，钉成形凹坑也可以人字形图案布置。Each staple in the staple cartridge can be aligned with the staple forming pockets of the anvil. In other words, the arrangement of the staple cavities and staples in the staple cartridge for the end effector may correspond to or match the arrangement of the staple forming pockets in the anvil of the end effector. More specifically, the angular orientation of each staple cavity may match the angular orientation of the corresponding staple forming pocket. For example, when the staple cavities are arranged in a herringbone pattern, the staple forming pockets may also be arranged in a herringbone pattern.

当钉从钉仓被驱动并与砧座成形接触时，钉可形成为击发构造。在各种实例中，击发构造可以是B形构造，其中钉腿的尖端朝向钉基部或冠部弯曲，以形成具有对称的上部环和下部环的大写字母B。在其他实例中，击发构造可以是改进的B形，诸如偏斜的B形构造，其中钉腿的至少一部分与钉基部扭转出平面，或者是不对称的B形构造，其中大写字母B的上部环和下部环是不对称的。可在成形的钉内捕获或夹紧组织。When the staples are driven from the staple cartridge into forming contact with the anvil, the staples may be formed into a fired configuration. In various examples, the firing configuration may be a B-shaped configuration in which the tips of the staple legs are curved toward the staple base or crown to form a capital B with symmetrical upper and lower rings. In other examples, the firing configuration may be a modified B-shaped configuration, such as a skewed B-shaped configuration in which at least a portion of the staple legs twist out of plane with the staple base, or an asymmetrical B-shaped configuration in which the upper portion of the capital letter B The ring and lower ring are asymmetric. Tissue can be captured or clamped within the formed staple.

钉仓中的钉和/或钉腔的布置可被构造成能够优化钉互补砧座的成形表面中的钉成形凹坑的对应布置。例如，钉仓中的钉的角度取向和间距可设计成优化砧座的成形表面。在某些实例中，砧座中的钉成形凹坑的占有面积可受到砧座的几何结构的限制。在钉成形凹坑相对于纵向轴线倾斜地取向的情况下，砧座的宽度可限制倾斜地取向的钉成形凹坑的尺寸和间距。例如，钉成形凹坑的中间排的宽度可限定中间排的一侧上的第一排(例如外排)与中间排的另一侧上的第二排(例如内排)之间的最小距离。此外，成排的钉成形凹坑被限制在砧座的内侧边缘(诸如刀狭槽)和砧座的外侧边缘之间。The arrangement of staples and/or staple cavities in the staple cartridge can be configured to optimize the corresponding arrangement of staple forming pockets in the forming surface of the complementary staple anvil. For example, the angular orientation and spacing of the staples in the staple cartridge can be designed to optimize the forming surface of the anvil. In certain examples, the footprint of the staple forming pockets in the anvil may be limited by the geometry of the anvil. Where the staple forming pockets are oriented obliquely with respect to the longitudinal axis, the width of the anvil may limit the size and spacing of the obliquely oriented staple forming pockets. For example, the width of the middle row of staple forming pockets may define the minimum distance between a first row (eg, outer row) on one side of the middle row and a second row (eg, inner row) on the other side of the middle row . Furthermore, the rows of staple forming pockets are constrained between the inside edge of the anvil (such as the knife slot) and the outside edge of the anvil.

在各种实例中，凹坑可沿砧座的钉成形表面相邻地嵌套。例如，中间凹坑可嵌套在内部凹坑和外部凹坑之间。凹坑的角度取向可逐排变化以便于其嵌套。例如，内排中的钉成形凹坑可以第一角度取向，中间排中的钉成形凹坑可以第二角度取向，并且外排中的钉成形凹坑可以第三角度取向。第一角度、第二角度和第三角度可以是不同的，这可促进钉成形凹坑的紧密布置。In various examples, the pockets may be nested adjacently along the staple forming surface of the anvil. For example, the middle pocket can be nested between the inner pocket and the outer pocket. The angular orientation of the dimples can be varied from row to row to facilitate their nesting. For example, the staple-forming pockets in the inner row may be oriented at a first angle, the staple-forming pockets in the middle row may be oriented at a second angle, and the staple-forming pockets in the outer row may be oriented at a third angle. The first angle, the second angle and the third angle may be different, which may promote a close arrangement of the staple forming pockets.

再次参考图27-31中所示的钉仓，可选择每个排中的钉和钉腔的变化角度，以优化钉成形凹坑在互补砧座中的嵌套。对于图27-31中所示的每个钉仓，互补的砧座可被构造成能够具有钉成形凹坑的对应布置。此外，互补砧座中的钉成形凹坑可比图27-31中所示的钉腔大以确保钉腿着陆或落入钉成形凹坑内。例如，钉腿可向外偏置，诸如在V形钉的情况下(参见图11)，并且钉成形凹坑的较大占有面积可在击发期间捕获向外偏置的钉腿。在各种实例中，钉成形凹坑可比对应的钉腔和/或钉长0.005英寸至0.015英寸。除此之外或另选地，每个钉成形凹坑的钉接收杯可比对应的钉腔宽0.005英寸至0.015英寸。在其他实例中，长度和 /或宽度的差异可小于0.005英寸或大于0.015英寸。Referring again to the staple cartridge shown in Figures 27-31, the varying angles of the staples and staple cavities in each row can be selected to optimize the nesting of the staple forming pockets in the complementary anvils. For each of the staple cartridges shown in Figures 27-31, the complementary anvils can be configured to have corresponding arrangements of staple forming pockets. Additionally, the staple forming pockets in the complementary anvils may be larger than the staple cavities shown in Figures 27-31 to ensure that the staple legs land or fall into the staple forming pockets. For example, the staple legs can be outwardly biased, such as in the case of V-shaped staples (see FIG. 11 ), and the larger footprint of the staple forming pockets can capture the outwardly biased staple legs during firing. In various examples, the staple forming pockets may be 0.005 inches to 0.015 inches longer than the corresponding staple cavities and/or staples. Additionally or alternatively, the staple receiving cup of each staple forming pocket may be 0.005 inches to 0.015 inches wider than the corresponding staple cavity. In other examples, the difference in length and/or width may be less than 0.005 inches or greater than 0.015 inches.

在钉的尺寸在钉仓内变化的实例中(参见例如图29-31)，钉成形凹坑的尺寸可在互补的砧座内相应地变化。改变钉成形凹坑的尺寸可进一步促进其嵌套。例如，在中间排中的钉成形凹坑比内排或外排中的钉成形凹坑短的情况下，可减小钉凹坑的中间排的宽度，这可最小化内排和外排之间的必要间距。In instances where the size of the staples varies within the staple cartridge (see, eg, FIGS. 29-31 ), the size of the staple forming pockets may vary accordingly within the complementary anvil. Varying the size of the staple forming pockets can further facilitate their nesting. For example, where the staple forming pockets in the middle row are shorter than the staple forming pockets in the inner or outer rows, the width of the middle row of staple pockets can be reduced, which can minimize the gap between the inner and outer rows necessary spacing.

钉成形凹坑的间距也可被构造成能够优化其嵌套。例如，布置在内排中的凹坑可相对于布置在外排中的凹坑纵向交错。此外，内排中的凹坑可部分地与外排中的凹坑纵向地重叠。中间排中的凹坑可相对于内排中的凹坑和外排中的凹坑纵向交错。例如，中间排中的凹坑可与外排中的凹坑和内排中的凹坑等距地纵向偏置。The spacing of the staple forming pockets can also be configured to optimize their nesting. For example, the dimples arranged in the inner row may be longitudinally staggered relative to the dimples arranged in the outer row. Furthermore, the dimples in the inner row may partially overlap longitudinally with the dimples in the outer row. The dimples in the middle row may be longitudinally staggered relative to the dimples in the inner row and the dimples in the outer row. For example, the dimples in the middle row may be longitudinally offset equidistant from the dimples in the outer row and the dimples in the inner row.

现在参见图80，示出了砧座3700。砧座3700可与钉仓3500(图30) 互补。例如，砧座3700中的钉成形凹坑3706的布置可对应于钉仓3500 中的钉3542和钉腔3510(图30)的布置。砧座3700包括钉成形表面3702 和纵向狭槽3704。纵向狭槽3704沿砧座3700的纵向轴线LA延伸。在某些实例中，击发元件和/或切割元件可在击发行程的至少一部分期间平移穿过纵向狭槽3704。钉成形凹坑3706限定在钉成形表面3702中。钉成形表面3702还包括围绕凹坑3706延伸的非成形部分3708。非成形部分 3708完全围绕图80中的每个凹坑3706延伸。换句话说，非成形部分3708 围绕钉成形凹坑3706。在其他实例中，两个或更多个相邻凹坑3706的至少一部分可邻接接触，使得非成形部分3708不被定位在两者间。Referring now to Figure 80, ananvil 3700 is shown.Anvil 3700 can be complementary to staple cartridge 3500 (FIG. 30). For example, the arrangement ofstaple forming pockets 3706 inanvil 3700 may correspond to the arrangement of staples 3542 andstaple cavities 3510 in staple cartridge 3500 (FIG. 30).Anvil 3700 includesstaple forming surface 3702 andlongitudinal slot 3704. Thelongitudinal slot 3704 extends along the longitudinal axis LA of theanvil 3700. In certain examples, the firing element and/or cutting element can translate throughlongitudinal slot 3704 during at least a portion of the firing stroke.Staple forming pockets 3706 are defined in thestaple forming surface 3702. Thestaple forming surface 3702 also includes anon-forming portion 3708 extending around thepockets 3706. Thenon-formed portion 3708 extends completely around eachdimple 3706 in FIG. 80 . In other words, thenon-formed portion 3708 forms thepocket 3706 around the staple. In other examples, at least a portion of two or moreadjacent pockets 3706 may be in abutting contact such that thenon-shaped portion 3708 is not positioned therebetween.

可优化钉成形表面3702的成形比。通过优化成形比，更多的钉可成形和/或成形为他们期望的构造。在某些实例中，砧座3700的非成形部分3708的表面区域可相对于钉成形凹坑3706被最小化。除此之外或另选地，钉成形凹坑3706的占有面积可延伸或扩大，以最大化钉成形表面 3702的被设计用于捕获和形成钉的部分。The forming ratio of thestaple forming surface 3702 can be optimized. By optimizing the forming ratio, more staples can be formed and/or formed into their desired configuration. In certain examples, the surface area of thenon-forming portion 3708 of theanvil 3700 can be minimized relative to thestaple forming pockets 3706. Additionally or alternatively, the footprint of thestaple forming pockets 3706 may be extended or enlarged to maximize the portion of thestaple forming surface 3702 designed to capture and form staples.

图80中示出的凹坑3706在纵向狭槽3704的第一侧上被布置成三个排3714a，3714b，3714c。第一排3714a是内排，第二排3714b是中间排，并且第三排3714c是外排。内部凹坑3706a被定位在内排3714a中，中间凹坑3706b被定位在中间排3714b中，并且外部凹坑3706c被定位在外排 3714c中。凹坑3706沿砧座3700的钉成形表面3702布置成人字形布置。尽管未在图80中示出，在至少一个实例中，狭槽3704的相对侧上的凹坑3706可形成纵向狭槽3704的第一侧上的凹坑3706的镜像反射。在其他实例中，钉成形表面3702中的凹坑3706的布置可相对于狭槽3704不对称，并且在某些实例中，砧座3700可不包括纵向狭槽3704。在各种实例中，凹坑3706可在狭槽3704的每个侧面上被布置成少于或多于三排。Thedimples 3706 shown in FIG. 80 are arranged in threerows 3714a, 3714b, 3714c on the first side of thelongitudinal slot 3704. Thefirst row 3714a is the inner row, thesecond row 3714b is the middle row, and thethird row 3714c is the outer row. Theinner pockets 3706a are positioned in theinner row 3714a, themiddle pockets 3706b are positioned in themiddle row 3714b, and theouter pockets 3706c are positioned in theouter row 3714c. Thepockets 3706 are arranged in a herringbone arrangement along thestaple forming surface 3702 of theanvil 3700. Although not shown in FIG. 80 , in at least one example, thedimples 3706 on opposite sides of theslot 3704 may form mirror reflections of thedimples 3706 on the first side of thelongitudinal slot 3704 . In other examples, the arrangement of thepockets 3706 in thestaple forming surface 3702 may be asymmetric relative to theslots 3704, and in some examples, theanvil 3700 may not include thelongitudinal slots 3704. In various examples, thedimples 3706 may be arranged in fewer or more than three rows on each side of theslot 3704.

每个凹坑3706包括周边3716，周边3716限定凹坑3706b的边界。每个凹坑3706还包括近侧杯3720，远侧杯3722，以及连接近侧杯3720和远侧杯3722的颈部部分3724。当钉被驱动成与钉成形表面3702成形接触时，近侧杯3720与近侧钉腿对准，并且远侧杯3722与远侧钉腿对准。钉腿的尖端被定位和被构造成能够着陆在相应的杯3720,3722中。换句话说，近侧杯3720被构造成能够接收近侧钉腿，并且远侧杯3722被构造成能够接收远侧钉腿。杯3720和3722还被构造成能够将钉腿朝向凹坑轴线PA和凹坑3806的中心部分(诸如颈部部分3724)引导或传送(funnel)，并使钉腿变形成所成形的构造。Eachpocket 3706 includes aperimeter 3716 that defines the boundary ofpocket 3706b. Eachpocket 3706 also includes aproximal cup 3720, adistal cup 3722, and aneck portion 3724 connecting theproximal cup 3720 and thedistal cup 3722. When the staples are driven into forming contact with thestaple forming surfaces 3702, theproximal cups 3720 are aligned with the proximal staple legs, and thedistal cups 3722 are aligned with the distal staple legs. The tips of the staple legs are positioned and configured to land in therespective cups 3720, 3722. In other words,proximal cup 3720 is configured to receive proximal staple legs, anddistal cup 3722 is configured to receive distal staple legs.Cups 3720 and 3722 are also configured to guide or funnel the staple legs toward pocket axis PA and a central portion of pocket 3806, such asneck portion 3724, and deform the staple legs into the shaped configuration.

凹坑3706的几何结构、间距和/或取向可逐排变化。凹坑轴线PA从近侧杯3720延伸，穿过颈部部分3724，并且延伸到每个凹坑3706的远侧杯3722。每排中的凹坑3706是平行的。例如，内部凹坑3706a相对于纵向轴线LA以角度A取向。换句话说，内部凹坑3706a的凹坑轴线(例如，PA_A)相对于纵向轴线LA以角度A取向。中间凹坑3706b相对于纵向轴线LA以角度B取向。换句话说，内部凹坑3706b的凹坑轴线(例如，PA_B)相对于纵向轴线LA以角度B取向。外部凹坑3706c相对于纵向轴线LA以角度C取向。换句话说，内部凹坑3706a的凹坑轴线(例如PA_C)相对于纵向轴线LA以角度C取向。The geometry, spacing and/or orientation of thedimples 3706 may vary from row to row. The dimple axis PA extends from theproximal cup 3720, through theneck portion 3724, and to thedistal cup 3722 of eachdimple 3706. Thedimples 3706 in each row are parallel. For example, theinner dimple 3706a is oriented at an angle A relative to the longitudinal axis LA. In other words, the dimple axis (eg, PA_A ) of theinner dimple 3706a is oriented at an angle A relative to the longitudinal axis LA.Intermediate pocket 3706b is oriented at angle B relative to longitudinal axis LA. In other words, the dimple axis (eg, PA_B ) of theinner dimple 3706b is oriented at an angle B relative to the longitudinal axis LA. Theouter pocket 3706c is oriented at an angle C relative to the longitudinal axis LA. In other words, the dimple axis (eg, PA_C ) of theinner dimple 3706a is oriented at an angle C relative to the longitudinal axis LA.

角度A、B和C可不同。内部凹坑3706a相对于外部凹坑3706c倾斜地取向。角度A小于角度C。因为外部凹坑3706c的轴线(例如，轴线 PA_C)不平行于内部凹坑3706a的轴线(例如，轴线PA_A)，所以砧座3700 中的钉成形凹坑3706形成修改的或偏斜的人字形图案。中间凹坑3706b 的凹坑轴线PA_B相对于内部凹坑3706a和外部凹坑3706c倾斜地取向。在其他实例中，中间凹坑3706b的凹坑轴线PA_B可取向成垂直于或基本上垂直于内部凹坑3706a或外部凹坑3706c。例如，角度B可以是角度A或 C的补角。Angles A, B and C can be different. Theinner pockets 3706a are oriented obliquely relative to theouter pockets 3706c. Angle A is less than angle C. Because the axis of theouter pocket 3706c (eg, axis PA_C ) is not parallel to the axis of theinner pocket 3706a (eg, axis PA_A ), the staple-formingpockets 3706 in theanvil 3700 form a modified or skewed human glyph pattern. The dimple axis PA_B of themiddle dimple 3706b is oriented obliquely with respect to theinner dimple 3706a and theouter dimple 3706c. In other examples, the dimple axis PA_B of themiddle dimple 3706b may be oriented perpendicular or substantially perpendicular to theinner dimple 3706a or theouter dimple 3706c. For example, angle B may be the supplement of angle A or C.

内部凹坑3706a具有长度L_A，中间凹坑3706b具有长度L_B，并且外部凹坑3706c具有长度L_C。长度L_C小于长度L_B和长度L_A。换句话说，外部凹坑3706c比中间凹坑3706b和内部凹坑3706a短。在某些实例中，长度L_A、L_B和L_C可以是不同的。在其他实例中，长度L_A、L_B和L_C可以是相同的。在其他实例中，长度L_B可小于长度L_A和/或L_B，和/或长度 L_A可小于长度L_A和/或L_C。可选择长度L_A、L_B和L_C以优化凹坑3706的嵌套。Inner dimple 3706a has length LA,middle dimple 3706b has length_LB , and outer dimple_3706c has length_LC . Length_LC is less than length_LB and length LA_. In other words, theouter pocket 3706c is shorter than themiddle pocket 3706b and theinner pocket 3706a. In some instances, lengths LA,_LB , and_LC may be different_. In other instances, the lengths LA,_LB and_LC may be the same_. In other examples, length_LB may be less than lengths LA and/or_LB , and/or length_LA may be less than lengths LA and_/ or_LC_. Lengths LA ,_LB and_LC can be selected to optimize the nesting of dimples₃₇₀₆ .

钉成形凹坑3706的间距也可被构造成能够优化其嵌套。例如，内部凹坑3706a可相对于外部凹坑3706c纵向交错。此外，内部凹坑3706a可部分地与外部凹坑3706c纵向重叠。参见图80，内部凹坑3706a的第一端部与外部凹坑3706c的对应端部纵向偏置距离X1_A/C。此外，内部凹坑 3706a的第二端部与外部凹坑3706c的对应端部纵向偏置距离X2_A/C。距离X2_A/C小于距离X1_A/C。在其他实例中，距离X2_A/C可等于或大于距离 X1_A/C。中间凹坑3706b相对于内部凹坑3706a和外部凹坑3706c纵向交错。更具体地，中间凹坑3706b在相邻的内部凹坑3706a之间以及相邻的外部凹坑3706c之间等距纵向地偏置。在其他实例中，中间凹坑3706b可在相邻的内部凹坑3706a之间以及相邻的外部凹坑3706c之间非等距地偏置。The spacing of thestaple forming pockets 3706 can also be configured to optimize their nesting. For example, theinner dimples 3706a may be longitudinally staggered relative to theouter dimples 3706c. Additionally, theinner dimple 3706a may partially overlap theouter dimple 3706c longitudinally. 80, the first end of theinner pocket 3706a is longitudinally offset from the corresponding end of theouter pocket 3706c by a distance X1_A/C . Additionally, the second end of theinner pocket 3706a is longitudinally offset from the corresponding end of theouter pocket 3706c by a distance X2A_/C . The distance X2_A/C is smaller than the distance X1_A/C . In other examples, distance X2_A/C may be equal to or greater than distance X1_A/C . Themiddle dimples 3706b are longitudinally staggered relative to theinner dimples 3706a andouter dimples 3706c. More specifically, themiddle dimples 3706b are longitudinally offset equidistantly between adjacentinner dimples 3706a and between adjacentouter dimples 3706c. In other examples, themiddle dimples 3706b may be non-equidistantly offset between adjacentinner dimples 3706a and between adjacentouter dimples 3706c.

凹坑3706的布置被构造成能够嵌套凹坑3706，使得凹坑3706配合在预定空间内。例如，在某些实例中，砧座的宽度可被最小化或以其他方式限制以配合在外科套管针内和/或狭窄的外科手术区域内，并且钉成形凹坑3706的布置(以及钉和/或钉腔的对应布置)可配合在狭窄的砧座内。The arrangement of thedimples 3706 is configured to nest thedimples 3706 such that thedimples 3706 fit within the predetermined space. For example, in certain instances, the width of the anvil may be minimized or otherwise limited to fit within a surgical trocar and/or within a narrow surgical field, and the placement of the staple forming pockets 3706 (and the staples and/or a corresponding arrangement of staple cavities) may fit within the narrow anvil.

现在参见图32-35C，示出了砧座3800的一部分中的钉成形凹坑3806。砧座3800包括钉成形表面3802和纵向狭槽3804。纵向狭槽3804沿砧座 3800的纵向轴线LA延伸。在某些实例中，击发元件和/或切割元件可在击发行程的至少一部分期间平移穿过纵向狭槽3804。钉成形凹坑3806限定在钉成形表面3802中，其还包括围绕凹坑3806延伸的非成形部分3808。非成形部分3808完全围绕每个凹坑3806延伸。换句话说，非成形部分3808围绕钉成形凹坑3806。在其他实例中，两个或更多个相邻凹坑的至少一部分可邻接接触，使得非成形部分不被定位在两者间。在某些实例中，非成形部分3808可延伸越过凹坑3806中的一个或多个。Referring now to Figures 32-35C, staple forming pockets 3806 in a portion ofanvil 3800 are shown.Anvil 3800 includesstaple forming surface 3802 andlongitudinal slot 3804. Thelongitudinal slot 3804 extends along the longitudinal axis LA of theanvil 3800. In certain examples, the firing element and/or cutting element can translate throughlongitudinal slot 3804 during at least a portion of the firing stroke. Staple forming pockets 3806 are defined in thestaple forming surface 3802, which also includes anon-forming portion 3808 extending around the pockets 3806. Thenon-shaped portion 3808 extends completely around each pocket 3806. In other words, thenon-formed portion 3808 forms the pocket 3806 around the staple. In other examples, at least a portion of two or more adjacent pockets may be in abutting contact such that a non-formed portion is not positioned therebetween. In certain examples,non-shaped portion 3808 may extend beyond one or more of dimples 3806 .

可优化钉成形表面3802的“成形比”(非成形部分3808与成形部分(即凹坑3806)的比率)。通过优化成形比，更多的钉可成形和/或成形为他们期望的构造。在某些实例中，砧座3800的非成形部分3808的表面区域可相对于钉成形凹坑3806被最小化。除此之外或另选地，钉成形凹坑3806的占有面积可延伸或扩大，以最大化钉成形表面3802的被设计用于捕获和形成钉的部分。例如，这种布置可防止无意的畸形钉，无论出于何种原因，钉在击发过程期间都会缺失或落在它们对应的成形凹坑之外。The "forming ratio" (the ratio of thenon-forming portion 3808 to the formed portion (ie, the dimples 3806 )) of thestaple forming surface 3802 can be optimized. By optimizing the forming ratio, more staples can be formed and/or formed into their desired configuration. In certain examples, the surface area of thenon-forming portion 3808 of theanvil 3800 can be minimized relative to the staple forming pockets 3806. Additionally or alternatively, the footprint of the staple forming pockets 3806 may be extended or enlarged to maximize the portion of thestaple forming surface 3802 designed to capture and form staples. For example, this arrangement prevents inadvertently misshapen staples, for whatever reason, missing or falling out of their corresponding shaped pockets during the firing process.

图32中示出的凹坑3806在纵向狭槽3804的第一侧上被布置成三个排3814a，3814b和3814c。第一排3814a是内排，第二排3814b是中间排，并且第三排3814c是外排。内部凹坑3806a被定位在内排3814a中，中间凹坑3806b被定位在中间排3814b中，并且外部凹坑3806c被定位在外排 3814c中。尽管未在图32中示出，在至少一个实例中，狭槽3804的相对侧上的凹坑3806可形成纵向狭槽3804的第一侧上的凹坑3806的镜像反射。在其他实例中，钉成形表面3802中的凹坑3806的布置可相对于狭槽3804不对称，并且在某些实例中，砧座3800可不包括纵向狭槽3804。在各种实例中，凹坑3806可在狭槽3804的每个侧面上被布置成少于或多于三排。The dimples 3806 shown in FIG. 32 are arranged in threerows 3814a, 3814b and 3814c on the first side of thelongitudinal slot 3804. Thefirst row 3814a is the inner row, thesecond row 3814b is the middle row, and thethird row 3814c is the outer row. Theinner pockets 3806a are positioned in theinner row 3814a, themiddle pockets 3806b are positioned in themiddle row 3814b, and theouter pockets 3806c are positioned in theouter row 3814c. Although not shown in FIG. 32 , in at least one example, the dimples 3806 on opposite sides of theslot 3804 may form mirror reflections of the dimples 3806 on the first side of thelongitudinal slot 3804 . In other examples, the arrangement of the pockets 3806 in thestaple forming surface 3802 can be asymmetric relative to theslots 3804, and in some examples, theanvil 3800 can not include thelongitudinal slots 3804. In various examples, the dimples 3806 may be arranged in fewer or more than three rows on each side of theslot 3804.

图32中示出的凹坑3806是相同的。限定在钉成形表面3802中的每个凹坑3806具有相同的几何结构。在其他实例中，凹坑3806的几何结构可沿砧座3800的长度逐排和/或纵向地变化。例如，在某些实例中，凹坑3806或其部分的深度可沿砧座3800的长度变化，以适应砧座和钉仓之间的间隙距离沿端部执行器和/或组织流的长度的变化，如本文所述。The dimples 3806 shown in Figure 32 are the same. Each pocket 3806 defined in thestaple forming surface 3802 has the same geometry. In other examples, the geometry of the pockets 3806 may vary row by row and/or longitudinally along the length of theanvil 3800 . For example, in certain instances, the depth of the pocket 3806, or a portion thereof, may vary along the length of theanvil 3800 to accommodate the variation of the gap distance between the anvil and the staple cartridge along the length of the end effector and/or tissue flow changes, as described herein.

示例性凹坑3806b在图33-35C中示出。凹坑3806b具有第一端部或近侧端部3810和第二端部或远侧端部3812。凹坑轴线PA在凹坑3806b 的近侧端部3810和远侧端部3814之间延伸。再次参见图32，每个相应排中的凹坑3806是平行的。例如，内部凹坑3806a的凹坑轴线(例如， PA_A)彼此平行，中间凹坑3806b的凹坑轴线(例如，PA_B)彼此平行，并且外部凹坑3806c的凹坑轴线(例如，PA_C)彼此平行。凹坑轴线PA 相对于狭槽3804倾斜地取向。此外，中间凹坑3806b的轴线PA_B分别取向成垂直于内部凹坑3806a和外部凹坑3806c的轴线PA_A和PA_C。这样，凹坑3806沿钉成形表面3802布置成人字形布置。Exemplary dimples 3806b are shown in Figures 33-35C. Thedimple 3806b has a first orproximal end 3810 and a second ordistal end 3812. The dimple axis PA extends between theproximal end 3810 and the distal end 3814 of thedimple 3806b. Referring again to Figure 32, the dimples 3806 in each respective row are parallel. For example, the dimple axes (eg, PA_A ) of theinner dimples 3806a are parallel to each other, the dimple axes (eg, PA_B ) of themiddle dimples 3806b are parallel to each other, and the dimple axes of theouter dimple 3806c (eg, PA_C ) are parallel to each other ) are parallel to each other. The pit axis PA is oriented obliquely with respect to theslot 3804 . Additionally, the axis PA_B of themiddle pocket 3806b is oriented perpendicular to the axes PA_A and PA_C of theinner pocket 3806a andouter pocket 3806c , respectively. In this way, the dimples 3806 are arranged in a herringbone arrangement along thestaple forming surface 3802.

凹坑3806b包括周边3816，周边3816限定凹坑3806b的边界。凹坑 3806b还包括近侧杯3820，远侧杯3822，以及连接近侧杯3820和远侧杯 3822的颈部部分3824。当钉被驱动成与钉成形表面3802成形接触时，近侧杯3820与近侧钉腿对准，并且远侧杯3822与远侧钉腿对准。钉腿的尖端被定位和被构造成能够着陆在相应的杯3820,3822中。换句话说，近侧杯3820被构造成能够接收近侧钉腿，并且远侧杯3822被构造成能够接收远侧钉腿。杯3820和3822还被构造成能够将钉腿朝向凹坑轴线 PA和凹坑3806的中心部分(诸如颈部部分3824)引导或传送(funnel)，并使钉腿变形成所成形的构造。Thedimple 3806b includes aperimeter 3816 that defines the boundary of thedimple 3806b. Thepocket 3806b also includes aproximal cup 3820, adistal cup 3822, and aneck portion 3824 connecting theproximal cup 3820 and thedistal cup 3822. When the staples are driven into forming contact with thestaple forming surfaces 3802, theproximal cups 3820 are aligned with the proximal staple legs and thedistal cups 3822 are aligned with the distal staple legs. The tips of the staple legs are positioned and configured to land in therespective cups 3820, 3822. In other words,proximal cup 3820 is configured to receive proximal staple legs, anddistal cup 3822 is configured to receive distal staple legs.Cups 3820 and 3822 are also configured to guide or funnel the staple legs toward pocket axis PA and a central portion of pocket 3806, such asneck portion 3824, and deform the staple legs into the shaped configuration.

凹坑3806包括用于钉腿的延伸着陆区。参考图33中示出的凹坑 3806b，凹坑3806b包括近侧延伸着陆区3830和远侧延伸着陆区3832。近侧延伸着陆区3830被定位在近侧杯3820的近侧部分中，并且远侧延伸着陆区3832被定位在远侧杯3822的远侧部分中。延伸着陆区3830和3832 限定基本上三角形的周边。此外，延伸着陆区3830和3832沿凹坑轴线 PA终止于一个点以形成凹坑3806b的拐角。The pockets 3806 include extended landing areas for the staple legs. Referring to thedimple 3806b shown in FIG. 33, thedimple 3806b includes a proximally extendinglanding zone 3830 and a distally extendinglanding zone 3832. A proximally extendinglanding zone 3830 is positioned in the proximal portion of theproximal cup 3820 and a distally extendinglanding zone 3832 is positioned in the distal portion of thedistal cup 3822.Extended landing zones 3830 and 3832 define a substantially triangular perimeter. Additionally,extended landing areas 3830 and 3832 terminate at a point along dimple axis PA to form the corners ofdimple 3806b.

在其他实例中，延伸着陆区3830和3832可限定例如直的和/或波状周边，并且可相对于凹坑轴线PA侧向和/或纵向延伸。在钉或其一部分在击发期间偏斜的实例中，延伸着陆区3830,3832可挽救或至少试图挽救偏斜的钉的成形。In other examples, theextended landing zones 3830 and 3832 may define, for example, a straight and/or wavy perimeter, and may extend laterally and/or longitudinally with respect to the dimple axis PA. In instances where a staple or a portion thereof deflects during firing, extending thelanding zones 3830, 3832 may rescue, or at least attempt to rescue, formation of the deflected staple.

主要参见图34，凹坑3806b的每个杯3820,3822限定入口斜坡3840 和出口斜坡3842。出口斜坡3842比入口斜坡3840更陡。当形成钉时，钉腿的尖端可沿入口斜坡3840进入相应的杯3820,3822并且沿出口斜坡 3842离开相应的杯3820,3822。在入口斜坡3840和出口斜坡3842之间的顶点3846处，钉腿的尖端朝向钉基部变形以呈现成形的构造，例如诸如B形或修改的B形。近侧杯3820在其顶点3846处限定相对于钉成形表面3802的非成形部分3808测量的近侧深度D₁，并且远侧杯3822在其顶点3846处限定相对于钉成形表面3802的非成形部分3808测量的远侧深度D₂。在凹坑3806b中，近侧深度D₁和远侧深度D₂相等。在其他实例中，近侧深度D₁和远侧深度D₂可以是不同的。Referring primarily to Figure 34, eachcup 3820, 3822 of thepocket 3806b defines aninlet ramp 3840 and anoutlet ramp 3842. Theexit slope 3842 is steeper than theentrance slope 3840. When the staples are formed, the tips of the staple legs can enter therespective cups 3820 , 3822 along the inlet ramps 3840 and exit therespective cups 3820 , 3822 along the outlet ramps 3842 . At the apex 3846 between theinlet ramp 3840 and theoutlet ramp 3842, the tips of the staple legs deform toward the staple base to assume a shaped configuration, such as a B-shape or a modified B-shape, for example. Theproximal cup 3820 defines a proximal depth D₁ at its apex 3846 relative to thenon-forming portion 3808 of thestaple forming surface 3802 , and thedistal cup 3822 defines a non-forming portion relative to thestaple forming surface 3802 at its apex 3846 3808 measured distal depth_D2 ._In dimple_3806b , proximal depth D1 and distal depth D2 are equal._In other examples, the proximal depth D1 and the distal depth_D2 may be different.

凹坑3806b还在近侧杯3820和远侧杯3822之间的颈部部分3824中限定桥接件3844。桥接件3844与钉成形表面3802的非成形部分3808偏置。更具体地，桥接件3844被定位在非成形部分3808下方或相对于非成形部分3808凹入。在其他实例中，桥接件3844可与非成形部分3808 对准和/或可从非成形部分3808朝向端部执行器的相对钳口突出。Thepocket 3806b also defines abridge 3844 in theneck portion 3824 between theproximal cup 3820 and thedistal cup 3822. Thebridges 3844 are offset from thenon-forming portion 3808 of thestaple forming surface 3802. More specifically, thebridges 3844 are positioned below or recessed relative to thenon-shaped portion 3808 . In other examples, thebridges 3844 can be aligned with thenon-shaped portion 3808 and/or can protrude from thenon-shaped portion 3808 toward the opposing jaws of the end effector.

主要参见图35A-35C，凹坑3806b包括侧壁3850。侧壁3850被取向成垂直于钉成形表面3802的非成形部分3808。侧壁3850朝向每个杯3820, 3822的中心区域3821变宽，并且从每个杯3820,3822的中心区域3821朝向颈部部分3824变窄。加宽的中心区域3821提供用于接收钉腿的尖端的扩大的占有面积。延伸着陆区3830,3832还扩大了用于接收钉尖端的相应杯3820,3822的占有面积。当杯3820,3822朝向颈部部分3824变窄时，杯3820,3822被构造成能够朝向和/或沿凹坑轴线PA传送和/或引导钉腿的尖端并且进入成形构造。随着杯3820和3822变宽并且然后朝向颈部部分3824变窄，凹坑3806b的周边3816限定轮廓或弧形轮廓。在其他实例中，凹坑3806b的周边3816可沿具有非圆角的线性非波状轮廓延伸。Referring primarily to FIGS. 35A-35C ,dimple 3806b includessidewalls 3850 . Thesidewall 3850 is oriented perpendicular to thenon-forming portion 3808 of thestaple forming surface 3802. Theside wall 3850 widens toward thecentral region 3821 of eachcup 3820, 3822 and narrows from thecentral region 3821 of eachcup 3820, 3822 toward theneck portion 3824. The widenedcentral region 3821 provides an enlarged footprint for receiving the tips of the staple legs. Extending thelanding zones 3830, 3832 also enlarges the footprint of therespective cups 3820, 3822 for receiving the tips of the staples. As thecups 3820, 3822 narrow toward theneck portion 3824, thecups 3820, 3822 are configured to transmit and/or guide the tips of the staple legs toward and/or along the pocket axis PA and into the shaped configuration. As thecups 3820 and 3822 widen and then narrow towards theneck portion 3824, theperimeter 3816 of thepocket 3806b defines a contour or arcuate profile. In other examples, theperimeter 3816 of thedimple 3806b may extend along a linear, non-wavy contour with non-rounded corners.

凹坑3806b在凹坑3806b的侧壁3850和底表面之间限定圆角3852(图 35A-35C)。圆角3852被构造成能够沿凹坑3806b中的期望路径引导钉腿。例如，如果钉腿沿圆角3852着陆或者被转移到圆角3852，则圆角3852 可平滑地引导钉腿朝向凹坑轴线PA。Thedimple 3806b defines afillet 3852 between thesidewall 3850 and the bottom surface of thedimple 3806b (FIGS. 35A-35C). Thefillets 3852 are configured to guide the staple legs along a desired path in thepockets 3806b. For example, if the staple legs land along thefillet 3852 or are transferred to thefillet 3852, thefillet 3852 may smoothly guide the staple legs toward the pocket axis PA.

再次参见图33，凹坑3806b关于凹坑轴线PA对称。例如，凹坑3806b 的周边3816关于凹坑轴线PA对称。此外，凹坑3806b关于穿过颈部部分3824并垂直于凹坑轴线PA的中心轴线CA对称。例如，每个凹坑3806 的周边3816关于中心轴线CA对称，并且近侧杯3820具有与远侧杯3822 相同的几何结构。Referring again to Figure 33, thedimple 3806b is symmetrical about the dimple axis PA. For example, theperimeter 3816 of thedimple 3806b is symmetrical about the dimple axis PA. Additionally, thedimple 3806b is symmetrical about a central axis CA that passes through theneck portion 3824 and is perpendicular to the dimple axis PA. For example, theperimeter 3816 of each pocket 3806 is symmetrical about the central axis CA, and theproximal cup 3820 has the same geometry as thedistal cup 3822.

在其他实例中，近侧杯3820可与远侧杯3822不同。例如，再次参见图34，远侧深度D₂可小于近侧深度D₁。在各种实例中，钉成形凹坑的深度的变化可适应砧座和钉仓之间的间隙距离在组织夹紧在两者间时沿端部执行器的长度的变化。例如，当砧座接近端部执行器的远侧端部时，砧座可从钉仓翘曲或弯曲。钉成形凹坑3806的深度的变化可被构造成能够确保考虑到砧座3800的预期或期望的翘曲或弯曲而保持适当的成形高度。In other examples, theproximal cup 3820 can be different from thedistal cup 3822. For example, referring again to Figure 34, the distal depth D2 may be less_than the proximal depth_D1 . In various examples, changes in the depth of the staple forming pockets can accommodate changes in the gap distance between the anvil and the staple cartridge along the length of the end effector when tissue is clamped therebetween. For example, the anvil may warp or bend from the staple cartridge as the anvil approaches the distal end of the end effector. Variation in the depth of the staple forming pockets 3806 can be configured to ensure that the proper forming height is maintained taking into account expected or expected warping or bending of theanvil 3800 .

除此之外或另选地，钉成形凹坑的深度的变化可适应相对于端部执行器的组织运动或流动。更具体地，当组织被夹紧在端部执行器的钳口之间时，被夹紧的组织中的流体可朝向相邻的未夹紧组织流动或运动。组织可朝向砧座3800的纵向侧面侧向流动，朝向砧座3800的远侧端部朝远侧流动，和/或朝向砧座3800的近侧端部朝近侧流动。在某些实例中，当切割边缘被朝远侧推进穿过组织时，组织可相对于砧座3800流动。在所述实例中，组织可侧向地、朝远侧和/或朝近侧流动，但由于切割边缘的远侧运动，所以组织主要朝远侧流动。在切割边缘朝近侧运动以切开组织的实例中，组织的运动或流动在切割行程期间通常是朝近侧的。凹坑3806中的不同深度D₁和D₁可适应组织的远侧流动，这可使嵌入其中的钉腿朝远侧移位或偏斜。Additionally or alternatively, variations in the depth of the staple forming pockets may accommodate tissue movement or flow relative to the end effector. More specifically, when tissue is clamped between the jaws of the end effector, fluid in the clamped tissue may flow or move toward adjacent unclamped tissue. Tissue may flow laterally toward the longitudinal sides of theanvil 3800 , distally toward the distal end of theanvil 3800 , and/or proximally toward the proximal end of theanvil 3800 . In certain instances, tissue can flow relative toanvil 3800 as the cutting edge is advanced distally through the tissue. In the example, the tissue may flow laterally, distally, and/or proximally, but the tissue flows primarily distally due to the distal movement of the cutting edge. In instances where the cutting edge is moved proximally to cut tissue, the movement or flow of the tissue is generally proximal during the cutting stroke._The different depths D1 and D1 in the pockets 3806 can accommodate the distal flow_of the tissue, which can displace or deflect the staple legs embedded therein distally.

在各种实例中，端部执行器的远侧端部处的组织运动或流动可大于端部执行器的近侧端部处的组织运动或流动。这种实例可因端部执行器内击发构件的远侧运动而出现。尽管击发构件被构造成能够随着其朝远侧运动而渐进地缝合和切入组织，但击发构件也可朝远侧推进或推动组织。此推动或推进效应可从端部执行器的近侧端部开始且可随着击发构件朝远侧运动而复合，使得在端部执行器的远侧端部处实现最大的推动或推进效应。因此，组织流动可朝向端部执行器的远侧端部增加。为了适应组织流动的这种增加，钉凹坑的几何结构可沿排的长度纵向变化。在钉仓的近侧杯和远侧杯不同以适应组织流动的实例中，凹坑不对称中的梯度可在一排凹坑内使用以补偿组织运动和钉移位中的梯度。In various examples, tissue movement or flow at the distal end of the end effector may be greater than tissue movement or flow at the proximal end of the end effector. Such an example may arise from distal movement of the firing member within the end effector. Although the firing member is configured to progressively staple and cut into tissue as it moves distally, the firing member may also advance or push tissue distally. This push or push effect can begin at the proximal end of the end effector and can compound as the firing member moves distally so that the maximum push or push effect is achieved at the distal end of the end effector. Thus, tissue flow may increase toward the distal end of the end effector. To accommodate this increase in tissue flow, the geometry of the staple pockets can vary longitudinally along the length of the row. In instances where the proximal and distal cups of the staple cartridge are different to accommodate tissue flow, gradients in pocket asymmetry may be used within a row of pockets to compensate for gradients in tissue motion and staple displacement.

在某些实例中，不同的钉几何结构可与不同的凹坑几何结构一起使用。2014年6月30日提交的名称为“FASTENER CARTRIDGES INCLUDING EXTENSIONS HAVING DIFFERENTCONFIGURATIONS”的美国专利申请号14/318,996中描述了使用不同的钉以适应沿端部执行器的长度的组织流动，该专利申请据此全文以引用方式并入本文。在其他实例中，可沿砧座的长度使用具有不同凹坑几何结构的相同钉。In some instances, different peg geometries may be used with different pocket geometries. The use of different tacks to accommodate tissue flow along the length of the end effector is described in U.S. Patent Application No. 14/318,996, filed June 30, 2014, entitled "FASTENER CARTRIDGES INCLUDING EXTENSIONS HAVING DIFFERENT CONFIGURATIONS," according to This entire text is incorporated herein by reference. In other examples, the same staple with different pocket geometries may be used along the length of the anvil.

再次参见图33，颈部部分3824限定宽度W_N，并且近侧杯3820和远侧杯3822限定宽度W_C。宽度W_N小于宽度W_C。因此，凹坑3806b的中心部分比近侧杯3820和远侧杯3822窄。颈部部分3824处的凹坑3806b 的变窄的周边3816在近侧杯3820的一部分和远侧杯3822的一部分之间限定接收半岛部3826。由于凹坑3806b的对称性，对称的接收半岛部3826 被定位在凹坑3806b的每个侧面上。接收半岛部3826由凹坑3806b的周边3816和切线轴线(例如，T_A、T_B1、T_B2和T_C)界定，该切线轴线与凹坑3806的侧面上的近侧杯3820和远侧杯3822的最宽部分相切。第一切线轴线T_B1被定位在凹坑3806b的第一侧上，并且第二切线轴线T_B2被定位在凹坑3806b的相对侧上。图33中示出的第一切线轴线T_B1和第二切线轴线T_B2与凹坑轴线PA_B平行。Referring again to Figure 33, theneck portion 3824 defines a width W_N , and theproximal cup 3820 and thedistal cup 3822 define a width W_C . The width W_N is smaller than the width W_C . Therefore, the central portion of thedimple 3806b is narrower than theproximal cup 3820 and thedistal cup 3822. The narrowedperimeter 3816 of thepocket 3806b at theneck portion 3824 defines a receivingpeninsula 3826 between a portion of theproximal cup 3820 and a portion of thedistal cup 3822. Due to the symmetry of thepocket 3806b,symmetrical receiving peninsulas 3826 are positioned on each side of thepocket 3806b. The receivingpeninsula 3826 is bounded by theperimeter 3816 of thepocket 3806b and tangential axes (eg, T_A , T_B1 , T_B2 and T_C ) that are connected to the proximal anddistal cups 3820 and 3820 on the sides of the pocket 3806 The widest part of the 3822 is tangent. The first tangential axis TB1 is positioned on a first side of the pocket_3806b , and the second tangential axis_TB2 is positioned on the opposite side of thepocket 3806b. The first tangential axis_TB1 and the second tangential axis_TB2 shown in FIG. 33 are parallel to the pit axis PA_B.

再次参见图32，凹坑3806的周边3816沿钉成形表面3802嵌套或互锁。具体地，每个凹坑3806延伸到相邻凹坑3806的接收半岛部3826中。例如，中间凹坑3806b嵌套在内部凹坑3806a和外部凹坑3806c之间。换句话说，中间凹坑3806b延伸到相邻内部凹坑3806a的接收半岛部3826 中并且延伸到相邻外部凹坑3806c的接收半岛部3826中。此外，内部凹坑3806a和外部凹坑3806b与中间凹坑3806b嵌套。更具体地，内部凹坑 3806a延伸到相邻中间凹坑3806b的接收半岛部3826中，并且外部凹坑 3806c延伸到相邻中间凹坑3806b的接收半岛部3826中。Referring again to FIG. 32, theperimeters 3816 of the pockets 3806 nest or interlock along thestaple forming surface 3802. Specifically, each pocket 3806 extends into the receivingpeninsula 3826 of an adjacent pocket 3806 . For example,middle pocket 3806b is nested betweeninner pocket 3806a andouter pocket 3806c. In other words, themiddle pocket 3806b extends into the receivingpeninsula 3826 of the adjacentinner pocket 3806a and into the receivingpeninsula 3826 of the adjacentouter pocket 3806c. In addition,inner dimple 3806a andouter dimple 3806b are nested withmiddle dimple 3806b. More specifically, theinner pocket 3806a extends into the receivingpeninsula 3826 of the adjacentmiddle pocket 3806b, and theouter pocket 3806c extends into the receivingpeninsula 3826 of the adjacentmiddle pocket 3806b.

中间凹坑3806b的远侧杯3822延伸跨过切线轴线T_A并进入相邻内部凹坑3806a的接收半岛部3826。此外，中间凹坑3806b的近侧杯3820 延伸跨过切线轴线T_C并进入相邻外部凹坑3806c的接收半岛部3826。另外，内部凹坑3806a的远侧杯3822延伸跨过切线轴线T_B1并进入相邻中间凹坑3806b的接收半岛部3826。此外，外部凹坑3806c的近侧杯3820 延伸跨过切线轴线T_B2并进入相邻中间凹坑3806b的接收半岛部3826。在各种实例中，中间凹坑3806b的远侧延伸着陆区3832被定位在内部凹坑3806a的接收半岛部3826中，中间凹坑3806b的近侧延伸着陆区3830 被定位在外部凹坑3806c的接收半岛部3826中，内部凹坑3806a的远侧延伸着陆区3832被定位在中间凹坑3806b的接收半岛部3826中，并且外部凹坑3806c的近侧延伸着陆区3830被定位在中间凹坑3806b的接收半岛部3826中。Thedistal cup 3822 of theintermediate pocket 3806b extends across the tangential axis_TA and into the receivingpeninsula 3826 of the adjacentinner pocket 3806a. Additionally, theproximal cup 3820 of the middle pocket_3806b extends across the tangential axis TC and into the receivingpeninsula 3826 of the adjacentouter pocket 3806c. Additionally, thedistal cup 3822 of the inner pocket_3806a extends across the tangential axis TB1 and into the receivingpeninsula 3826 of the adjacentintermediate pocket 3806b. Additionally, theproximal cup 3820 of theouter pocket 3806c extends across the tangential axis_TB2 and into the receivingpeninsula 3826 of the adjacentintermediate pocket 3806b. In various examples, the distally extendinglanding zone 3832 of themiddle pocket 3806b is positioned in the receivingpeninsula 3826 of theinner pocket 3806a and the proximally extendinglanding zone 3830 of themiddle pocket 3806b is positioned in theouter pocket 3806c In the receivingpeninsula 3826, thedistally extending land 3832 of theinner pocket 3806a is positioned in the receivingpeninsula 3826 of themiddle pocket 3806b, and the proximally extending landing 3830 of theouter pocket 3806c is positioned within themiddle pocket 3806b The receivingpeninsula section 3826.

凹坑3806的几何结构便于凹坑3806在钉成形表面3802中的嵌套。例如，因为凹坑3806包括在两个扩大的杯3820和3822之间的变窄的颈部部分3824，所以另一个凹坑3806的扩大的杯3820,3822中的一个可定位成邻近变窄的颈部部分3824。例如，扩大的杯3820,3822中的一个可与相邻的凹坑3806的一部分对准和/或被其接收。在所述实例中，可优化由凹坑3806覆盖的钉成形表面3802的表面区域。例如，由凹坑3806 覆盖的钉成形表面3802的表面区域被最大化。钉成形表面3802的“成形比”是非成形部分3808与成形部分(即，凹坑3806)的比率。成形比为约1.7:1。在其他实例中，成形比可小于1.7:1或大于1.7:1。例如，在至少一个实例中，钉成形表面3802的50％以上可用钉成形凹坑3806覆盖。The geometry of the dimples 3806 facilitates the nesting of the dimples 3806 in thestaple forming surface 3802. For example, because dimple 3806 includes a narrowedneck portion 3824 between twoenlarged cups 3820 and 3822, one of theenlarged cups 3820, 3822 of another dimple 3806 may be positioned adjacent to the narrowedNeck section 3824. For example, one of theenlarged cups 3820, 3822 may be aligned with and/or received by a portion of the adjacent pocket 3806. In the example, the surface area of thestaple forming surface 3802 covered by the dimples 3806 can be optimized. For example, the surface area of thestaple forming surface 3802 covered by the dimples 3806 is maximized. The "formation ratio" of thestaple forming surface 3802 is the ratio of thenon-formed portion 3808 to the formed portion (ie, the dimples 3806). The forming ratio is about 1.7:1. In other examples, the forming ratio may be less than 1.7:1 or greater than 1.7:1. For example, in at least one example, more than 50% of thestaple forming surface 3802 may be covered with the staple forming pockets 3806.

本文讨论的钉成形凹坑的嵌套可指相邻凹坑周边的嵌套。例如，在第一凹坑限定向内轮廓的情况下，即轮廓朝向凹坑轴线向内延伸，相邻的第二凹坑可突出朝向和/或进入与向内轮廓相邻的区域。除此之外或另选地，第二凹坑的一部分诸如第二凹坑的端部可与第一凹坑的变窄区域对准。因此，与第二凹坑的端部与第一凹坑的较宽区域对准相比，第二凹坑可定位成更靠近第一凹坑的凹坑轴线。Nesting of staple forming pockets discussed herein may refer to nesting around the perimeter of adjacent pockets. For example, where a first dimple defines an inward profile, ie the profile extends inwardly towards the dimple axis, an adjacent second dimple may protrude towards and/or into an area adjacent to the inward profile. Additionally or alternatively, a portion of the second dimple, such as an end of the second dimple, may be aligned with the narrowed area of the first dimple. Thus, the second dimple may be positioned closer to the dimple axis of the first dimple than when the end of the second dimple is aligned with a wider area of the first dimple.

现在参见图36-39C，示出了砧座3900的一部分中的钉成形凹坑3906。砧座3900包括钉成形表面3902和纵向狭槽3904。纵向狭槽3904沿砧座 3900的纵向轴线LA延伸。在某些实例中，击发元件和/或切割元件可在击发行程的至少一部分期间平移穿过纵向狭槽3904。钉成形凹坑3906限定在钉成形表面3902中。钉成形表面3902还包括围绕凹坑3906延伸的非成形部分3908。非成形部分3908完全围绕图36中的每个凹坑3906延伸。换句话说，非成形部分3908围绕钉成形凹坑3906。在其他实例中，两个或更多个相邻凹坑3906的至少一部分可邻接接触，使得非成形部分 3908不被定位在两者间。Referring now to Figures 36-39C,staple forming pockets 3906 in a portion ofanvil 3900 are shown.Anvil 3900 includesstaple forming surface 3902 andlongitudinal slot 3904. Thelongitudinal slot 3904 extends along the longitudinal axis LA of theanvil 3900. In certain examples, the firing element and/or cutting element can translate throughlongitudinal slot 3904 during at least a portion of the firing stroke.Staple forming pockets 3906 are defined in thestaple forming surface 3902. Thestaple forming surface 3902 also includes anon-forming portion 3908 extending around thepockets 3906. Thenon-formed portion 3908 extends completely around eachpocket 3906 in FIG. 36 . In other words, thenon-formed portion 3908 forms thepocket 3906 around the staple. In other examples, at least a portion of two or moreadjacent pockets 3906 may be in abutting contact such that thenon-formed portion 3908 is not positioned therebetween.

可优化钉成形表面3902的成形比。通过优化成形比，更多的钉可成形和/或成形为他们期望的构造。在某些实例中，砧座3900的非成形部分3908的表面区域可相对于钉成形凹坑3906被最小化。除此之外或另选地，钉成形凹坑3906的占有面积可延伸或扩大，以最大化钉成形表面 3902的被设计用于捕获和形成钉的部分。The forming ratio of thestaple forming surface 3902 can be optimized. By optimizing the forming ratio, more staples can be formed and/or formed into their desired configuration. In certain examples, the surface area of thenon-forming portion 3908 of theanvil 3900 can be minimized relative to thestaple forming pockets 3906. Additionally or alternatively, the footprint of thestaple forming pockets 3906 may be extended or enlarged to maximize the portion of thestaple forming surface 3902 designed to capture and form staples.

图36中示出的凹坑3906在纵向狭槽3904的第一侧上被布置成三个排3914a，3914b，3914c。第一排3914a是内排，第二排3914b是中间排，并且第三排3914c是外排。内部凹坑3906a被定位在内排3914a中，中间凹坑3906b被定位在中间排3914b中，并且外部凹坑3906c被定位在外排 3914c中。类似于砧座3800，凹坑3906沿砧座3900的钉成形表面3902布置成人字形布置。尽管未在图36中示出，在至少一个实例中，狭槽 3904的相对侧上的凹坑3906可形成纵向狭槽3904的第一侧上的凹坑 3906的镜像反射。在其他实例中，钉成形表面3902中的凹坑3906的布置可相对于狭槽3904不对称，并且在某些实例中，砧座3900可不包括纵向狭槽3904。在各种实例中，凹坑3906可在狭槽3904的每个侧面上被布置成少于或多于三排。Thedimples 3906 shown in FIG. 36 are arranged in threerows 3914a, 3914b, 3914c on the first side of thelongitudinal slot 3904. Thefirst row 3914a is the inner row, thesecond row 3914b is the middle row, and thethird row 3914c is the outer row. Theinner pockets 3906a are positioned in theinner row 3914a, themiddle pockets 3906b are positioned in themiddle row 3914b, and theouter pockets 3906c are positioned in theouter row 3914c. Similar to theanvil 3800, thepockets 3906 are arranged in a herringbone arrangement along thestaple forming surface 3902 of theanvil 3900. Although not shown in FIG. 36 , in at least one example, thepits 3906 on opposite sides of theslot 3904 may form mirror reflections of thepits 3906 on the first side of thelongitudinal slot 3904. In other examples, the arrangement of thepockets 3906 in thestaple forming surface 3902 can be asymmetric relative to theslots 3904, and in some examples, theanvil 3900 can not include thelongitudinal slots 3904. In various examples, thedimples 3906 may be arranged in fewer or more than three rows on each side of theslot 3904.

图36中示出的凹坑3906是相同的。限定在钉成形表面3802中的每个凹坑3906具有相同的几何结构。在其他实例中，凹坑3906的几何结构可沿砧座3900的长度逐排和/或纵向地变化。例如，在某些实例中，凹坑3906或其部分的深度可沿砧座3900的长度变化，以适应砧座和钉仓之间的间隙距离沿端部执行器和/或组织流的长度的变化，如本文所述。Thedimples 3906 shown in Figure 36 are the same. Eachpocket 3906 defined in thestaple forming surface 3802 has the same geometry. In other examples, the geometry of thepockets 3906 may vary row by row and/or longitudinally along the length of theanvil 3900. For example, in certain instances, the depth of thepocket 3906, or a portion thereof, may vary along the length of theanvil 3900 to accommodate the change in the gap distance between the anvil and the staple cartridge along the length of the end effector and/or tissue flow. changes, as described herein.

示例性凹坑3906在37-39C中示出。凹坑3906b具有第一端部或近侧端部3910和第二端部或远侧端部3912。凹坑轴线PA(图37)在凹坑3906b 的近侧端部3910和远侧端部3912之间延伸。凹坑3906b包括周边3916，周边3916限定凹坑3906的边界。凹坑3906b还包括近侧杯3920，远侧杯 3922，以及连接近侧杯3920和远侧杯3922的颈部部分3924。当钉被驱动成与钉成形表面3902成形接触时，近侧杯3920与近侧钉腿对准，并且远侧杯3922与远侧钉腿对准。杯3920和3922被构造成能够将钉腿朝向凹坑轴线PA和凹坑3906的中心部分(诸如颈部部分3924)引导或传送，并使钉腿变形成所成形的构造。Exemplary dimples 3906 are shown in 37-39C. Thedimple 3906b has a first orproximal end 3910 and a second ordistal end 3912. The dimple axis PA (FIG. 37) extends between theproximal end 3910 and thedistal end 3912 of thedimple 3906b. Thedimple 3906b includes aperimeter 3916 that defines the boundary of thedimple 3906 . Thepocket 3906b also includes aproximal cup 3920, adistal cup 3922, and aneck portion 3924 connecting theproximal cup 3920 and thedistal cup 3922. When the staples are driven into forming contact with thestaple forming surfaces 3902, theproximal cups 3920 are aligned with the proximal staple legs and thedistal cups 3922 are aligned with the distal staple legs.Cups 3920 and 3922 are configured to guide or transport the staple legs toward pocket axis PA and a central portion ofpocket 3906, such asneck portion 3924, and deform the staple legs into a shaped configuration.

主要参见图38，凹坑3906b的每个杯3920,3922限定入口斜坡3940 和出口斜坡3942。出口斜坡3942比入口斜坡3940更陡。当形成钉时，钉腿的尖端可沿入口斜坡3940进入相应的杯3920,3922，并且沿出口斜坡3942离开相应的杯3920,3922。在入口斜坡3940和出口斜坡3942之间的顶点3946处，钉腿的尖端朝向钉基部变形以呈现成形的构造，例如诸如B形或修改的B形。近侧杯3920在其顶点3946处限定相对于钉成形表面3902的非成形部分3908测量的近侧深度D₁，并且远侧杯3922在其顶点3946处限定相对于钉成形表面3902的非成形部分3908测量的远侧深度D₂。在凹坑3906中，近侧深度D₁和远侧深度D₂相等。在其他实例中，近侧深度D₁和远侧深度D₂可以是不同的。凹坑3906b还在近侧杯 3920和远侧杯3922之间的颈部部分3924中限定桥接件3944。桥接件3944 与钉成形表面3902的非成形部分3908偏置。更具体地，桥接件3944被定位在非成形部分3908下方或相对于非成形部分3908凹入。Referring primarily to Figure 38, eachcup 3920, 3922 of thepocket 3906b defines aninlet ramp 3940 and anoutlet ramp 3942. Theexit slope 3942 is steeper than theentrance slope 3940. As the staples are formed, the tips of the staple legs can enter therespective cups 3920 , 3922 along theinlet ramp 3940 and exit therespective cups 3920 , 3922 along theoutlet ramp 3942 . At the apex 3946 between theinlet ramp 3940 and theoutlet ramp 3942, the tips of the staple legs deform toward the staple base to assume a shaped configuration, such as, for example, a B-shape or a modified B-shape. Theproximal cup 3920 defines a proximal depth D₁ at its apex 3946 relative to thenon-forming portion 3908 of thestaple forming surface 3902 , and thedistal cup 3922 defines a non-forming portion relative to thestaple forming surface 3902 at its apex 3946 3908 measured distal depth_D2 ._Indimple 3906, proximal depth D1 and distal depth_D2 are equal._In other examples, the proximal depth D1 and the distal depth_D2 may be different. Thepocket 3906b also defines abridge 3944 in theneck portion 3924 between theproximal cup 3920 and thedistal cup 3922. Thebridge 3944 is offset from thenon-forming portion 3908 of thestaple forming surface 3902. More specifically, thebridges 3944 are positioned below or recessed relative to thenon-shaped portion 3908 .

主要参见图39A-39C，凹坑3906b包括侧壁3950。侧壁3950被取向成垂直于钉成形表面3902的非成形部分3908。侧壁3950从每个杯3920, 3922的外端朝向颈部部分3924线性地变窄。因此，杯3920,3922的最宽部分分别位于凹坑3906b的近侧端部3910和远侧端部3912处。凹坑3906b 的轮廓3916限定蝴蝶结形状周边。近侧端部和远侧端部3910,3912处的加宽区域提供了用于接收钉腿尖端的扩大的占有面积。在各种实例中，杯3920和3922的加宽部分限定用于接收钉尖端的延伸着陆区。当杯3920, 3922朝向颈部部分3924变窄时，杯3920,3922被构造成能够朝向和/或沿凹坑轴线PA传送和/或引导钉腿的尖端并且进入成形构造。凹坑3906b 沿凹坑3906b的侧面限定倒角边缘3954。倒角边缘3954用于扩大凹坑3906b的占有面积并引导钉腿的尖端朝向凹坑轴线PA。Referring primarily to FIGS. 39A-39C ,dimple 3906b includessidewalls 3950 . Thesidewall 3950 is oriented perpendicular to thenon-forming portion 3908 of thestaple forming surface 3902. Thesidewall 3950 narrows linearly from the outer end of eachcup 3920, 3922 toward theneck portion 3924. Thus, the widest portions of thecups 3920, 3922 are located at theproximal end 3910 and thedistal end 3912 of thepocket 3906b, respectively. Thecontour 3916 of thedimple 3906b defines a bowtie-shaped perimeter. The widened areas at the proximal anddistal ends 3910, 3912 provide an enlarged footprint for receiving the tips of the staple legs. In various examples, the widened portions ofcups 3920 and 3922 define extended landing zones for receiving staple tips. As thecups 3920, 3922 narrow toward theneck portion 3924, thecups 3920, 3922 are configured to transmit and/or guide the tips of the staple legs toward and/or along the pocket axis PA and into the shaped configuration. Thedimple 3906b defines a chamferededge 3954 along the sides of thedimple 3906b. The chamferededge 3954 serves to expand the footprint of thepocket 3906b and guide the tips of the legs toward the pocket axis PA.

再次参见图37，凹坑3906b关于凹坑轴线PA对称。例如，凹坑3906b 的周边3916关于凹坑轴线PA对称。此外，凹坑3906b关于穿过颈部部分3924并垂直于凹坑轴线PA的中心轴线CA对称。例如，凹坑3906b 的周边3916关于中心轴线CA对称，并且近侧杯3920具有与远侧杯3922 相同的几何结构。在其他实例中，近侧杯3920可与远侧杯3922不同。例如，再次参见图38，远侧深度D₂可小于近侧深度D₁，以适应砧座和钉仓和/或组织流之间的间隙距离的变化，如本文所述。Referring again to Figure 37, thedimple 3906b is symmetrical about the dimple axis PA. For example, theperimeter 3916 of thedimple 3906b is symmetrical about the dimple axis PA. Furthermore, thedimple 3906b is symmetrical about a central axis CA passing through theneck portion 3924 and perpendicular to the dimple axis PA. For example, theperimeter 3916 of thepocket 3906b is symmetrical about the central axis CA, and theproximal cup 3920 has the same geometry as thedistal cup 3922. In other examples, theproximal cup 3920 can be different from thedistal cup 3922. For example, referring again to Figure 38, the distal depth D2 may be less_than the proximal depth_D1 to accommodate variations in the gap distance between the anvil and the staple cartridge and/or tissue flow, as described herein.

再次参见图37，颈部部分3924的宽度小于杯3920和3922的宽度。因此，凹坑3906b的中心部分比近侧杯3920和远侧杯3922窄。颈部部分 3924处的凹坑3906b的变窄的周边3916在近侧杯3920的一部分和远侧杯 3922的一部分之间限定接收半岛部3926。由于凹坑3906b的对称性，对称的接收半岛部3926被定位在凹坑3906b的每个侧面上。接收半岛部3926由凹坑3906b的周边3916和切线轴线(例如，T_B1和T_B2)界定，该切线轴线与凹坑3906b的侧面上的近侧杯3920和远侧杯3922的最宽部分相切。第一切线轴线T_B1被定位在凹坑3906b的第一侧上，并且第二切线轴线T_B2被定位在凹坑3906b的相对侧上。第一切线轴线T_B1和第二切线轴线T_B2平行于凹坑轴线PA。Referring again to FIG. 37, the width of theneck portion 3924 is smaller than the width of thecups 3920 and 3922. Therefore, the central portion of thedimple 3906b is narrower than theproximal cup 3920 and thedistal cup 3922. The narrowedperimeter 3916 of thepocket 3906b at theneck portion 3924 defines a receivingpeninsula 3926 between a portion of theproximal cup 3920 and a portion of thedistal cup 3922. Due to the symmetry of thepocket 3906b,symmetrical receiving peninsulas 3926 are positioned on each side of thepocket 3906b. The receivingpeninsula 3926 is bounded by theperimeter 3916 of thepocket 3906b and a tangential axis (eg, T_B1 and T_B2 ) that is opposite the widest portions of the proximal anddistal cups 3920 and 3922 on the sides of thepocket 3906b. cut. The first tangential axis TB1 is positioned on a first side of the pocket_3906b , and the second tangential axis_TB2 is positioned on the opposite side of thepocket 3906b. The first tangential axis_TB1 and the second tangential axis_TB2 are parallel to the pit axis PA.

再次参见图36，每个凹坑3906朝向相邻凹坑3906的接收半岛部3926 延伸。例如，中间凹坑3906b与内部凹坑3906a和外部凹坑3906c的颈部部分3924对准。此外，内部凹坑3906a和外部凹坑3906b朝向中间凹坑 3906b中的一个的接收半岛部3926延伸。更具体地，中间凹坑3906b的凹坑轴线PA分别与相邻的内部凹坑3906a和外部凹坑3906c的颈部部分3924对准，内部凹坑3906a的凹坑轴线PA与相邻的中间凹坑3906b的颈部部分3924对准，并且外部凹坑3906c的凹坑轴线PA与相邻的中间凹坑3906b的颈部部分3924对准。在某些实例中，凹坑3906中的一个或多个的一部分可延伸到相邻凹坑3906的接收半岛部中。Referring again to FIG. 36 , eachpocket 3906 extends toward the receivingpeninsula 3926 of anadjacent pocket 3906 . For example, themiddle pocket 3906b is aligned with theneck portions 3924 of theinner pocket 3906a andouter pocket 3906c. Additionally, theinner pocket 3906a and theouter pocket 3906b extend toward the receivingpeninsula 3926 of one of theintermediate pockets 3906b. More specifically, the pocket axis PA of themiddle pocket 3906b is aligned with theneck portions 3924 of the adjacentinner pocket 3906a andouter pocket 3906c, respectively, and the pocket axis PA of theinner pocket 3906a is aligned with the adjacent middle pocket. Theneck portions 3924 of thepockets 3906b are aligned, and the pocket axis PA of theouter pockets 3906c is aligned with theneck portions 3924 of the adjacentintermediate pockets 3906b. In some examples, a portion of one or more of thepockets 3906 may extend into the receiving peninsulas ofadjacent pockets 3906 .

凹坑3906的几何结构便于凹坑3906在钉成形表面3902中的紧密布置。例如，因为凹坑3906包括在两个扩大的杯3920和3922之间的变窄的颈部部分3924，所以另一个凹坑3906的扩大的杯3920,3922可定位成邻近变窄的颈部部分3924。例如，扩大的杯3920,3922可与相邻的凹坑 3906的一部分对准和/或被其接收。因此，可优化由凹坑3906覆盖的钉成形表面3902的表面区域。例如，由凹坑3906覆盖的钉成形表面3902 的表面区域被最大化。“成形比”是非成形部分3908与成形部分(即，凹坑3906)的比率。在各种实例中，例如，成形比可以是至少1:1。The geometry of thedimples 3906 facilitates the close placement of thedimples 3906 in thestaple forming surface 3902. For example, becausepocket 3906 includes a narrowedneck portion 3924 between twoenlarged cups 3920 and 3922, enlargedcups 3920, 3922 of anotherpocket 3906 may be positioned adjacent to the narrowedneck portion 3924. For example, theenlarged cups 3920, 3922 can be aligned with and/or received by a portion of anadjacent pocket 3906. Accordingly, the surface area of thestaple forming surface 3902 covered by thedimples 3906 can be optimized. For example, the surface area of thestaple forming surface 3902 covered by thedimples 3906 is maximized. The "forming ratio" is the ratio of theunshaped portion 3908 to the formed portion (ie, the dimples 3906). In various examples, for example, the forming ratio may be at least 1:1.

在某些实例中，尽管凹坑3906定位成紧密靠近彼此，但由于颈部部分3924变窄，因此在相邻凹坑3906之间存在用于非成形部分3908的空间。例如，非成形部分3908可在内部凹坑3906a的颈部部分3924和相邻中间凹坑3906b的远侧杯3922之间延伸。相邻凹坑3906之间的非成形部分3908可在凹坑3906之间提供足够的间距，以加强和/或增强砧座3900。In some instances, although thedimples 3906 are positioned in close proximity to each other, due to the narrowing of theneck portions 3924, there is space betweenadjacent dimples 3906 for thenon-formed portions 3908. For example, thenon-shaped portion 3908 may extend between theneck portion 3924 of theinner pocket 3906a and thedistal cup 3922 of the adjacentintermediate pocket 3906b. Thenon-formed portions 3908 betweenadjacent pockets 3906 may provide sufficient spacing between thepockets 3906 to strengthen and/or strengthen theanvil 3900.

现在参见图40-43C，示出了砧座4000的一部分中的钉成形凹坑4006。凹坑4006及其在砧座4000中的布置在许多方面类似于凹坑3906及其在砧座3900中的布置。例如，砧座4000包括钉成形表面4002和纵向狭槽 4004。纵向狭槽4004沿砧座4000的纵向轴线LA延伸。在某些实例中，击发元件和/或切割元件可在击发行程的至少一部分期间平移穿过纵向狭槽4004。钉成形凹坑4006限定在钉成形表面4002中。钉成形表面4002 还包括围绕凹坑4006延伸的非成形部分4008。非成形部分4008完全围绕图40中的每个凹坑4006延伸。换句话说，非成形部分4008围绕钉成形凹坑4006。在其他实例中，两个或更多个相邻凹坑4006的至少一部分可邻接接触，使得非成形部分4008不被定位在两者间。Referring now to Figures 40-43C,staple forming pockets 4006 in a portion ofanvil 4000 are shown. Thedimples 4006 and their arrangement in theanvil 4000 are similar in many respects to thedimples 3906 and their arrangement in theanvil 3900 . For example, theanvil 4000 includes astaple forming surface 4002 and alongitudinal slot 4004. Thelongitudinal slot 4004 extends along the longitudinal axis LA of theanvil 4000 . In certain examples, the firing element and/or cutting element can translate throughlongitudinal slot 4004 during at least a portion of the firing stroke.Staple forming pockets 4006 are defined in thestaple forming surface 4002. Thestaple forming surface 4002 also includes anon-forming portion 4008 extending around thedimples 4006 . Anon-shaped portion 4008 extends completely around eachpocket 4006 in FIG. 40 . In other words, thenon-formed portion 4008 forms thepocket 4006 around the staple. In other examples, at least a portion of two or moreadjacent pockets 4006 may be in abutting contact such that thenon-shaped portion 4008 is not positioned therebetween.

可优化钉成形表面4002的成形比。通过优化成形比，更多的钉可成形和/或成形为他们期望的构造。在某些实例中，砧座4000的非成形部分4008的表面区域可相对于钉成形凹坑4006被最小化。除此之外或另选地，钉成形凹坑4006的占有面积可延伸或扩大，以最大化钉成形表面 4002的被设计用于捕获和形成钉的部分。The forming ratio of thestaple forming surface 4002 can be optimized. By optimizing the forming ratio, more staples can be formed and/or formed into their desired configuration. In certain examples, the surface area of thenon-forming portion 4008 of theanvil 4000 may be minimized relative to thestaple forming pockets 4006. Additionally or alternatively, the footprint of thestaple forming pockets 4006 may be extended or enlarged to maximize the portion of thestaple forming surface 4002 designed to capture and form staples.

凹坑4006在纵向狭槽4004的第一侧上被布置成内排4014a、中间排 4014b和外排4014c。内部凹坑4006a被定位在内排4014a中，中间凹坑 4006b被定位在中间排4014b中，并且外部凹坑4006c被定位在外排4014c 中。类似于砧座3800，凹坑4006沿砧座4000的钉成形表面4002布置成人字形布置。尽管未在图40中示出，在至少一个实例中，狭槽4004的相对侧上的凹坑4006可形成纵向狭槽4004的第一侧上的凹坑4006的镜像反射。在其他实例中，钉成形表面4002中的凹坑4006的布置可相对于狭槽4004不对称，并且在某些实例中，砧座4000可不包括纵向狭槽 4004。在各种实例中，凹坑4006可在狭槽4004的每个侧面上被布置成少于或多于三排。Thedimples 4006 are arranged on the first side of thelongitudinal slot 4004 in aninner row 4014a, amiddle row 4014b and anouter row 4014c. Theinner pocket 4006a is positioned in theinner row 4014a, themiddle pocket 4006b is positioned in themiddle row 4014b, and theouter pocket 4006c is positioned in theouter row 4014c. Similar to theanvil 3800, thepockets 4006 are arranged in a herringbone arrangement along thestaple forming surface 4002 of theanvil 4000. Although not shown in FIG. 40 , in at least one example, thedimples 4006 on opposite sides of theslot 4004 may form mirror reflections of thedimples 4006 on the first side of thelongitudinal slot 4004 . In other examples, the arrangement of thepockets 4006 in thestaple forming surface 4002 may be asymmetric relative to theslots 4004, and in some examples, theanvil 4000 may not include thelongitudinal slots 4004. In various examples, thedimples 4006 may be arranged in fewer or more than three rows on each side of theslot 4004 .

图40中示出的凹坑4006是相同的。限定在钉成形表面4002中的每个凹坑4006具有相同的几何结构。在其他实例中，凹坑4006的几何结构可沿砧座4000的长度逐排和/或纵向地变化。例如，在某些实例中，凹坑4006或其部分的深度可沿砧座4000的长度变化，以适应砧座和钉仓之间的间隙距离沿端部执行器和/或组织流的长度的变化，如本文所述。Thedimples 4006 shown in Figure 40 are the same. Eachpocket 4006 defined in thestaple forming surface 4002 has the same geometry. In other examples, the geometry of thepockets 4006 may vary row by row and/or longitudinally along the length of theanvil 4000 . For example, in certain instances, the depth of thepocket 4006, or a portion thereof, may vary along the length of theanvil 4000 to accommodate the variation of the gap distance between the anvil and the staple cartridge along the length of the end effector and/or tissue flow changes, as described herein.

示例性凹坑4006b在图41-43C中示出。凹坑4006b具有第一端部或近侧端部4010和第二端部或远侧端部4012。凹坑轴线PA(图41)在凹坑4006b的近侧端部4010和远侧端部4012之间延伸。凹坑4006b包括周边4016，周边4016限定凹坑4006b的边界。凹坑4006b还包括近侧杯4020，远侧杯4022，以及连接近侧杯4020和远侧杯4022的颈部部分4024。当钉被驱动成与钉成形表面4002成形接触时，近侧杯4020与近侧钉腿对准，并且远侧杯4022与远侧钉腿对准。杯4020和4022被构造成能够将钉腿朝向凹坑轴线PA和凹坑4006的中心部分(诸如颈部部分4024)引导或传送，并使钉腿变形成所成形的构造。Exemplary dimples 4006b are shown in Figures 41-43C. Thedimple 4006b has a first orproximal end 4010 and a second ordistal end 4012. The dimple axis PA (FIG. 41) extends between theproximal end 4010 and thedistal end 4012 of thedimple 4006b. Thedimple 4006b includes aperimeter 4016 that defines the boundary of thedimple 4006b. Thepocket 4006b also includes aproximal cup 4020, adistal cup 4022, and aneck portion 4024 connecting theproximal cup 4020 and thedistal cup 4022. When the staples are driven into forming contact with thestaple forming surfaces 4002, theproximal cups 4020 are aligned with the proximal staple legs and thedistal cups 4022 are aligned with the distal staple legs.Cups 4020 and 4022 are configured to guide or transport the staple legs toward pocket axis PA and a central portion ofpocket 4006, such asneck portion 4024, and deform the staple legs into the shaped configuration.

主要参见图42，凹坑4006b的每个杯4020,4022限定入口斜坡4040 和出口斜坡4042。当形成钉时，钉腿的尖端可沿入口斜坡4040进入相应的杯4020,4022，并且沿出口斜坡4042离开相应的杯4020,4022。在入口斜坡4040和出口斜坡4042之间的顶点4046处，钉腿的尖端朝向钉基部变形以呈现成形的构造，例如诸如B形或修改的B形。凹坑4006b还在近侧杯4020和远侧杯4022之间限定桥接件4044。桥接件4044与非成形部分4008偏置。更具体地，桥接件4044被定位在非成形部分4008下方或相对于非成形部分4008凹入。Referring primarily to Figure 42, eachcup 4020, 4022 of thepocket 4006b defines aninlet ramp 4040 and anoutlet ramp 4042. As the staples are formed, the tips of the staple legs can enter therespective cups 4020 , 4022 along theinlet ramp 4040 and exit therespective cups 4020 , 4022 along theoutlet ramp 4042 . At the apex 4046 between theinlet ramp 4040 and theoutlet ramp 4042, the tips of the staple legs deform toward the staple base to assume a shaped configuration, such as a B-shape or a modified B-shape, for example. Thedimple 4006b also defines abridge 4044 between theproximal cup 4020 and thedistal cup 4022.Bridge 4044 is offset fromnon-formed portion 4008 . More specifically, thebridges 4044 are positioned below or recessed relative to thenon-shaped portion 4008 .

主要参见图43A-43C，凹坑4006b包括侧壁4050，侧壁4050被取向成垂直于钉成形表面4002的非成形部分4008。侧壁4050从每个杯4020, 4022的外端朝向颈部部分4024变窄。因此，杯4020,4022的最宽部分分别位于凹坑4006b的近侧端部4010和远侧端部4012处。凹坑4006b的轮廓4016限定蝴蝶结形状周边。近侧端部和远侧端部4010,4012处的加宽区域提供了用于接收钉腿尖端的扩大的占有面积。在各种实例中，杯4020, 4022的加宽部分限定用于接收钉尖端的延伸着陆区。当杯4020,4022朝向颈部部分4024变窄时，杯4020,4022被构造成能够朝向和/或沿凹坑轴线PA传送和/或引导钉腿的尖端并且进入成形构造。Referring primarily to FIGS. 43A-43C , thepocket 4006b includes asidewall 4050 oriented perpendicular to thenon-forming portion 4008 of the staple-formingsurface 4002 . Theside wall 4050 narrows from the outer end of eachcup 4020, 4022 toward theneck portion 4024. Thus, the widest portions of thecups 4020, 4022 are located at theproximal end 4010 and thedistal end 4012 of thepocket 4006b, respectively. Thecontour 4016 of thedimple 4006b defines a bowtie-shaped perimeter. The widened areas at the proximal anddistal ends 4010, 4012 provide an enlarged footprint for receiving the tips of the staple legs. In various examples, the widened portions ofcups 4020, 4022 define extended landing zones for receiving staple tips. As thecups 4020, 4022 narrow toward theneck portion 4024, thecups 4020, 4022 are configured to transmit and/or guide the tips of the staple legs toward and/or along the pocket axis PA and into the shaped configuration.

凹坑4006b沿凹坑4006b的侧面限定倒角边缘4054。另外，凹坑4006b 在其底表面4058中包括凹槽4056。凹槽4056从近侧杯4020延伸越过桥接件4024并进入远侧杯4022。凹槽4056被构造成能够在钉腿运动到变形构型时约束和引导钉腿。Thedimple 4006b defines a chamferededge 4054 along the sides of thedimple 4006b. Additionally,dimple 4006b includesgrooves 4056 inbottom surface 4058 thereof. Thegroove 4056 extends from theproximal cup 4020 over thebridge 4024 and into thedistal cup 4022. Thegrooves 4056 are configured to constrain and guide the staple legs as they move to the deformed configuration.

在各种实例中，凹槽4056的直径可小于与凹槽4056接合的钉的直径。例如，钉可具有至少0.0079英寸的直径，并且凹槽4056的直径可小于0.0079英寸。凹槽4056的直径可为约0.007英寸、约0.005英寸或小于 0.005英寸。在某些实例中，例如，钉的直径可大于0.0079英寸，诸如约 0.0089英寸或约0.0094英寸。在各种实例中，U形钉的直径可小于0.0079 英寸或大于0.0094英寸。在端部执行器中，其中不同的钉几何结构与相同的钉成形凹坑几何结构一起使用，凹坑中的凹槽的宽度可小于最小直径的钉。在其他实例中，凹槽4056的宽度可在排内和/或逐排改变钉-钉。In various examples, the diameter of thegrooves 4056 may be smaller than the diameter of the staples with which thegrooves 4056 engage. For example, the spikes can have a diameter of at least 0.0079 inches, and thegrooves 4056 can be less than 0.0079 inches in diameter. The diameter of thegrooves 4056 may be about 0.007 inches, about 0.005 inches, or less than 0.005 inches. In certain instances, for example, the diameter of the staples may be greater than 0.0079 inches, such as about 0.0089 inches or about 0.0094 inches. In various examples, the diameter of the staple can be less than 0.0079 inches or greater than 0.0094 inches. In end effectors where different staple geometries are used with the same staple forming pocket geometry, the width of the grooves in the pockets may be smaller than the smallest diameter staple. In other examples, the width of thegrooves 4056 may vary from staple to staple within a row and/or from row to row.

再次参见图41，凹坑4006b关于凹坑轴线PA对称。例如，凹坑4006b 的周边4016关于凹坑轴线PA对称。此外，凹坑4006b关于穿过颈部部分4024并垂直于凹坑轴线PA的中心轴线CA对称。例如，凹坑4006b 的周边4016关于中心轴线CA对称，并且近侧杯4020具有与远侧杯4022 相同的几何结构。在其他实例中，近侧杯4020可与远侧杯4022不同。例如，再次参见图42，远侧深度D₂可小于近侧深度D₁，以适应砧座和钉仓和/或组织流之间的间隙距离的变化，如本文所述。Referring again to Figure 41, thedimple 4006b is symmetrical about the dimple axis PA. For example, theperimeter 4016 of thedimple 4006b is symmetrical about the dimple axis PA. Furthermore, thedimple 4006b is symmetrical about a central axis CA passing through theneck portion 4024 and perpendicular to the dimple axis PA. For example, theperimeter 4016 of thepocket 4006b is symmetrical about the central axis CA, and theproximal cup 4020 has the same geometry as thedistal cup 4022. In other examples, theproximal cup 4020 can be different from thedistal cup 4022. For example, referring again to Figure 42, the distal depth D2 may be less_than the proximal depth_D1 to accommodate variations in the gap distance between the anvil and the staple cartridge and/or tissue flow, as described herein.

再次参见图41，凹坑4006b的颈部部分4024比近侧杯4020和远侧杯4022窄。凹坑4006b的变窄的周边4016在近侧杯4020的一部分和远侧杯4022的一部分之间限定接收半岛部4026。由于凹坑4006b的对称性，对称的接收半岛部4026被定位在凹坑4006b的每个侧面上。接收半岛部 4026由凹坑4006b的周边4016和切线轴线(例如，T_B1和T_B2)界定，该切线轴线与凹坑4006b的侧面上的近侧杯4020和远侧杯4022的最宽部分相切。第一切线轴线T_B1被定位在凹坑4006b的第一侧上，并且第二切线轴线T_B2被定位在凹坑4006b的相对侧上。图41中示出的第一切线轴线 T_B1和第二切线轴线T_B2与凹坑轴线PA平行。Referring again to FIG. 41 , theneck portion 4024 of thepocket 4006b is narrower than theproximal cup 4020 and thedistal cup 4022. The narrowedperimeter 4016 of thepocket 4006b defines a receivingpeninsula 4026 between a portion of theproximal cup 4020 and a portion of thedistal cup 4022. Due to the symmetry of thepocket 4006b,symmetrical receiving peninsulas 4026 are positioned on each side of thepocket 4006b. The receivingpeninsula 4026 is bounded by theperimeter 4016 of thepocket 4006b and a tangential axis (eg, T_B1 and T_B2 ) that intersects the widest portions of the proximal anddistal cups 4020 and 4022 on the sides of thepocket 4006b. cut. The first tangential axis TB1 is positioned on a first side of the dimple_4006b , and the second tangential axis_TB2 is positioned on the opposite side of thedimple 4006b. The first tangential axis_TB1 and the second tangential axis_TB2 shown in FIG. 41 are parallel to the pit axis PA.

再次参见图40，每个凹坑4006朝向相邻凹坑4006的接收半岛部4026 延伸。例如，中间凹坑4006b与内部凹坑4006a和外部凹坑4006c的颈部部分4024对准。此外，内部凹坑4006a和外部凹坑4006b朝向中间凹坑 4006b中的一个的接收半岛部4026延伸。更具体地，内部凹坑4006a与相邻中间凹坑4006b的颈部部分4024对准，并且外部凹坑4006c与相邻中间凹坑4006b的颈部部分4024对准。在某些实例中，凹坑4006的一部分可延伸到相邻凹坑4006的接收半岛部4026中。类似于砧座3900中的凹坑3906，凹坑4006的几何结构便于凹坑4006在钉成形表面4002中的紧密布置。“成形比”是非成形部分4008与成形部分(即，凹坑4006) 的比率。在各种实例中，例如，成形比可以是至少1:1。Referring again to FIG. 40 , eachdimple 4006 extends toward the receivingpeninsula 4026 of anadjacent dimple 4006 . For example, themiddle pocket 4006b is aligned with theneck portions 4024 of theinner pocket 4006a andouter pocket 4006c. Additionally, theinner pocket 4006a and theouter pocket 4006b extend toward the receivingpeninsula 4026 of one of theintermediate pockets 4006b. More specifically, theinner pocket 4006a is aligned with theneck portion 4024 of the adjacentmiddle pocket 4006b, and theouter pocket 4006c is aligned with theneck portion 4024 of the adjacentmiddle pocket 4006b. In some examples, a portion of adimple 4006 may extend into the receivingpeninsula 4026 of anadjacent dimple 4006 . Similar to thepockets 3906 in theanvil 3900, the geometry of thepockets 4006 facilitates the close placement of thepockets 4006 in thestaple forming surface 4002. The "forming ratio" is the ratio of theunshaped portion 4008 to the formed portion (ie, the dimples 4006). In various examples, for example, the forming ratio may be at least 1:1.

现在参见图44-47C，示出了砧座4100的一部分中的钉成形凹坑4106。凹坑4106及其在砧座4100中的布置在许多方面类似于凹坑4006及其在砧座4000中的布置。例如，砧座4100包括钉成形表面4102和纵向狭槽 4104。纵向狭槽4104沿砧座4100的纵向轴线LA延伸。在某些实例中，击发元件和/或切割元件可在击发行程的至少一部分期间平移穿过纵向狭槽4104。钉成形凹坑4106限定在钉成形表面4102中。钉成形表面4102 还包括围绕凹坑4106延伸的非成形部分4108。非成形部分4108完全围绕图41中的每个凹坑4106延伸。换句话说，非成形部分4108围绕钉成形凹坑4106。在其他实例中，两个或更多个相邻凹坑4106的至少一部分可邻接接触，使得非成形部分4108不被定位在两者间。Referring now to Figures 44-47C, staple forming pockets 4106 in a portion ofanvil 4100 are shown. The dimples 4106 and their arrangement in theanvil 4100 are similar in many respects to thedimples 4006 and their arrangement in theanvil 4000 . For example, theanvil 4100 includes astaple forming surface 4102 and alongitudinal slot 4104. Thelongitudinal slot 4104 extends along the longitudinal axis LA of theanvil 4100 . In certain examples, the firing element and/or cutting element can translate throughlongitudinal slot 4104 during at least a portion of the firing stroke. Staple forming pockets 4106 are defined in thestaple forming surface 4102. Thestaple forming surface 4102 also includes anon-forming portion 4108 extending around the pockets 4106 . Thenon-formed portion 4108 extends completely around each pocket 4106 in FIG. 41 . In other words, thenon-formed portion 4108 forms the pocket 4106 around the staple. In other examples, at least a portion of two or more adjacent pockets 4106 may be in abutting contact such that thenon-shaped portion 4108 is not positioned therebetween.

可优化钉成形表面4102的成形比。通过优化成形比，更多的钉可成形和/或成形为他们期望的构造。在某些实例中，砧座4100的非成形部分4108的表面区域可相对于钉成形凹坑4106被最小化。除此之外或另选地，钉成形凹坑4106的占有面积可延伸或扩大，以最大化钉成形表面 4102的被设计用于捕获和形成钉的部分。The forming ratio of thestaple forming surface 4102 can be optimized. By optimizing the forming ratio, more staples can be formed and/or formed into their desired configuration. In certain examples, the surface area of thenon-forming portion 4108 of theanvil 4100 may be minimized relative to the staple forming pockets 4106. Additionally or alternatively, the footprint of the staple forming pockets 4106 may be extended or enlarged to maximize the portion of thestaple forming surface 4102 designed to capture and form staples.

图44中示出的凹坑4106在纵向狭槽4104的第一侧上被布置成内排 4114a、中间排4114b和外排4114c。内部凹坑4106a被定位在内排4114a 中，中间凹坑4106b被定位在中间排4114b中，并且外部凹坑4106c被定位在外排4114c中。类似于砧座3800，凹坑4106沿砧座4100的钉成形表面4102布置成人字形布置。尽管未在图44中示出，在至少一个实例中，狭槽4104的相对侧上的凹坑4106可形成纵向狭槽4104的第一侧上的凹坑4106的镜像反射。在其他实例中，钉成形表面4102中的凹坑4106的布置可相对于狭槽4104不对称，并且在某些实例中，砧座4100可不包括纵向狭槽4104。在各种实例中，凹坑4106可在狭槽4104的每个侧面上被布置成少于或多于三排。The dimples 4106 shown in Figure 44 are arranged on the first side of thelongitudinal slot 4104 in an inner row 4114a, amiddle row 4114b and anouter row 4114c. Theinner pockets 4106a are positioned in the inner row 4114a, themiddle pockets 4106b are positioned in themiddle row 4114b, and theouter pockets 4106c are positioned in theouter row 4114c. Similar to theanvil 3800, the pockets 4106 are arranged in a herringbone arrangement along thestaple forming surface 4102 of theanvil 4100. Although not shown in FIG. 44 , in at least one example, the dimples 4106 on opposite sides of theslot 4104 may form mirror reflections of the dimples 4106 on the first side of thelongitudinal slot 4104 . In other examples, the arrangement of the pockets 4106 in thestaple forming surface 4102 may be asymmetric relative to theslots 4104 , and in some examples, theanvil 4100 may not include thelongitudinal slots 4104 . In various examples, the dimples 4106 may be arranged in fewer or more than three rows on each side of theslot 4104 .

图44中示出的凹坑4106是相同的。限定在钉成形表面4102中的每个凹坑4106具有相同的几何结构。在其他实例中，凹坑4106的几何结构可沿砧座4100的长度逐排和/或纵向地变化。例如，在某些实例中，凹坑4106或其部分的深度可沿砧座4100的长度变化，以适应砧座和钉仓之间的间隙距离沿端部执行器和/或组织流的长度的变化，如本文所述。The dimples 4106 shown in Figure 44 are the same. Each pocket 4106 defined in thestaple forming surface 4102 has the same geometry. In other examples, the geometry of the pockets 4106 may vary row by row and/or longitudinally along the length of theanvil 4100 . For example, in certain instances, the depth of the pockets 4106 or portions thereof may vary along the length of theanvil 4100 to accommodate the difference in the gap distance between the anvil and the staple cartridge along the length of the end effector and/or tissue flow changes, as described herein.

示例性凹坑4106b在图45-47C中示出。凹坑4106b具有第一端部或近侧端部4110和第二端部或远侧端部4112。凹坑轴线PA(图45)在凹坑4106b的近侧端部4110和远侧端部4112之间延伸。凹坑4106b包括周边4116，周边4116限定凹坑4106b的边界。凹坑4106b还包括近侧杯4120，远侧杯4122，以及连接近侧杯4120和远侧杯4122的颈部部分4124。当钉被驱动成与钉成形表面4102成形接触时，近侧杯4120与近侧钉腿对准，并且远侧杯4122与远侧钉腿对准。杯4120，4122被构造成能够将钉腿朝向凹坑轴线PA和凹坑4106的中心部分(诸如颈部部分4124)引导或传送，并使钉腿变形成所成形的构造。Exemplary dimples 4106b are shown in Figures 45-47C. Thedimple 4106b has a first orproximal end 4110 and a second ordistal end 4112. The dimple axis PA (FIG. 45) extends between theproximal end 4110 and thedistal end 4112 of thedimple 4106b. Thedimple 4106b includes aperimeter 4116 that defines the boundary of thedimple 4106b. Thepocket 4106b also includes aproximal cup 4120, adistal cup 4122, and aneck portion 4124 connecting theproximal cup 4120 and thedistal cup 4122. When the staples are driven into forming contact with thestaple forming surfaces 4102, theproximal cups 4120 are aligned with the proximal staple legs and thedistal cups 4122 are aligned with the distal staple legs. Thecups 4120, 4122 are configured to guide or transport the staple legs toward the pocket axis PA and the central portion of the pocket 4106, such as theneck portion 4124, and deform the staple legs into the shaped configuration.

主要参见图46，凹坑4106b的每个杯4120,4122限定入口斜坡4140 和出口斜坡4142。出口斜坡4142比入口斜坡4140更陡。当形成钉时，钉腿的尖端可沿入口斜坡4140进入相应的杯4120,4122并且沿出口斜坡 4142离开相应的杯4120,4122。在入口斜坡4140和出口斜坡4142之间的顶点4146处，钉腿的尖端朝向钉基部变形以呈现成形的构造，例如诸如B形或修改的B形。凹坑4106b还在近侧杯4120和远侧杯4122之间的颈部部分4124中限定桥接件4144。桥接件4144与非成形部分4108偏置。更具体地，桥接件4144被定位在非成形部分4108下方或相对于非成形部分4108凹入。Referring primarily to Figure 46, eachcup 4120, 4122 of thepocket 4106b defines aninlet ramp 4140 and anoutlet ramp 4142. Theexit slope 4142 is steeper than theentrance slope 4140. As the staples are formed, the tips of the staple legs can enter therespective cups 4120, 4122 along the inlet ramps 4140 and exit therespective cups 4120, 4122 along the outlet ramps 4142. At the apex 4146 between theinlet ramp 4140 and theoutlet ramp 4142, the tips of the staple legs deform toward the staple base to assume a shaped configuration, such as a B-shape or a modified B-shape, for example. Thepocket 4106b also defines abridge 4144 in theneck portion 4124 between theproximal cup 4120 and thedistal cup 4122.Bridge 4144 is offset fromnon-formed portion 4108. More specifically, thebridges 4144 are positioned below or recessed relative to thenon-shaped portion 4108 .

主要参见图47A-47C，凹坑4106b包括侧壁4150，侧壁4150被取向成垂直于钉成形表面4102的非成形部分4108。侧壁4150从每个杯4120, 4122的外端朝向颈部部分4124变窄。因此，杯4120和4122的最宽部分分别位于凹坑4106b的近侧端部4110和远侧端部4112处。凹坑4106b的轮廓4116限定蝴蝶结形状周边。近侧端部和远侧端部4110,4112处的加宽区域提供了用于接收钉腿尖端的扩大的占有面积。在各种实例中，杯 4120,4122的加宽部分限定用于接收钉尖端的延伸着陆区。当杯4120,4122 朝向颈部部分4124变窄时，杯4120,4122被构造成能够朝向和/或沿凹坑轴线PA传送和/或引导钉腿的尖端并且进入成形构造。Referring primarily to FIGS. 47A-47C , thedimple 4106b includes asidewall 4150 oriented perpendicular to thenon-forming portion 4108 of thestaple forming surface 4102 . Theside wall 4150 narrows from the outer end of eachcup 4120, 4122 toward theneck portion 4124. Thus, the widest portions ofcups 4120 and 4122 are located atproximal end 4110 anddistal end 4112 ofpocket 4106b, respectively. Thecontour 4116 of thedimple 4106b defines a bowtie-shaped perimeter. The widened areas at the proximal anddistal ends 4110, 4112 provide an enlarged footprint for receiving the tips of the staple legs. In various examples, the widened portions of thecups 4120, 4122 define extended landing zones for receiving the tips of the staples. As thecups 4120, 4122 narrow toward theneck portion 4124, thecups 4120, 4122 are configured to transmit and/or guide the tips of the staple legs toward and/or along the pocket axis PA and into the shaped configuration.

再次参见图47A-47C，凹坑4106b沿凹坑4106b的侧面限定倒角边缘 4154。另外，凹坑4106b在其底表面4158中包括凹槽4156。凹槽4156限定在近侧杯4120和远侧杯4122中。在所示实施方案中，凹槽4156不延伸跨过凹坑4106b的桥接件4144。凹槽4156被构造成能够在钉腿运动到变形构型时约束和引导钉腿。例如，当钉沿入口斜坡4140和出口斜坡 4142的至少一部分运动时，钉腿可滑过凹槽4156。在各种实例中，凹槽 4156的直径可小于与凹槽4156接合的钉的直径。在端部执行器中，其中不同的钉几何结构与相同的钉成形凹坑几何结构一起使用，凹坑中的凹槽的宽度可小于最小直径的钉。在各种实例中，钉腿在到达桥接件4144 之前朝向钉基部变形，并且因此不与凹坑4106b的桥接件4144接合。Referring again to Figures 47A-47C, thedimple 4106b defines a chamferededge 4154 along the sides of thedimple 4106b. Additionally,dimple 4106b includesgrooves 4156 inbottom surface 4158 thereof.Recesses 4156 are defined inproximal cup 4120 anddistal cup 4122. In the embodiment shown, thegrooves 4156 do not extend across thebridges 4144 of thepockets 4106b. Thegrooves 4156 are configured to constrain and guide the staple legs as they move to the deformed configuration. For example, the staple legs can slide through thegrooves 4156 as the staples move along at least a portion of theinlet ramp 4140 andoutlet ramp 4142. In various examples, the diameter of thegrooves 4156 can be smaller than the diameter of the staples with which thegrooves 4156 engage. In end effectors where different staple geometries are used with the same staple forming pocket geometry, the width of the grooves in the pockets may be smaller than the smallest diameter staple. In various examples, the staple legs deform toward the staple bases before reaching thebridges 4144, and thus do not engage thebridges 4144 of thepockets 4106b.

再次参见图45，凹坑4106b关于凹坑轴线PA对称。例如，凹坑4106b 的周边4116关于凹坑轴线PA对称。此外，凹坑4106b关于穿过颈部部分4124并垂直于凹坑轴线PA的中心轴线CA对称。例如，凹坑4106b 的周边4116关于中心轴线CA对称，并且近侧杯4120具有与远侧杯4122 相同的几何结构。在其他实例中，近侧杯4120可与远侧杯4122不同。例如，再次参见图42，远侧深度D₂可小于近侧深度D₁，以适应砧座和钉仓和/或组织流之间的间隙距离的变化，如本文所述。Referring again to Figure 45, thedimple 4106b is symmetrical about the dimple axis PA. For example, theperimeter 4116 of thedimple 4106b is symmetrical about the dimple axis PA. Furthermore, thedimple 4106b is symmetrical about a central axis CA passing through theneck portion 4124 and perpendicular to the dimple axis PA. For example, theperimeter 4116 of thepocket 4106b is symmetrical about the central axis CA, and theproximal cup 4120 has the same geometry as thedistal cup 4122. In other examples, theproximal cup 4120 can be different from thedistal cup 4122. For example, referring again to Figure 42, the distal depth D2 may be less_than the proximal depth_D1 to accommodate variations in the gap distance between the anvil and the staple cartridge and/or tissue flow, as described herein.

再次参见图45，凹坑4106b的颈部部分4124比近侧杯4120和远侧杯4122窄。凹坑4106b的变窄的周边4116在近侧杯4120的一部分和远侧杯4122的一部分之间限定接收半岛部4126。由于凹坑4106b的对称性，对称的接收半岛部4126被定位在凹坑4106b的每个侧面上。接收半岛部 4126由凹坑4106b的周边4116和切线轴线(例如，T_B1和T_B2)界定，该切线轴线与凹坑4106b的侧面上的近侧杯4120和远侧杯4122的最宽部分相切。第一切线轴线T_B1被定位在凹坑4106b的第一侧上，并且第二切线轴线T_B2被定位在凹坑4106b的相对侧上。图45中示出的第一切线轴线 T_B1和第二切线轴线T_B2与凹坑轴线PA平行。Referring again to FIG. 45, theneck portion 4124 of thepocket 4106b is narrower than theproximal cup 4120 and thedistal cup 4122. The narrowedperimeter 4116 of thepocket 4106b defines a receivingpeninsula 4126 between a portion of theproximal cup 4120 and a portion of thedistal cup 4122. Due to the symmetry of thepocket 4106b,symmetrical receiving peninsulas 4126 are positioned on each side of thepocket 4106b. The receivingpeninsula 4126 is bounded by theperimeter 4116 of thepocket 4106b and a tangential axis (eg, T_B1 and T_B2 ) that intersects the widest portions of the proximal anddistal cups 4120 and 4122 on the sides of thepocket 4106b cut. The first tangential axis TB1 is positioned on a first side of the pocket_4106b and the second tangential axis_TB2 is positioned on the opposite side of thepocket 4106b. The first tangential axis_TB1 and the second tangential axis_TB2 shown in FIG. 45 are parallel to the pit axis PA.

再次参见图44，每个凹坑4106朝向相邻凹坑4106的接收半岛部4126 延伸。例如，中间凹坑4106b与内部凹坑4106a和外部凹坑4106c的颈部部分4124对准。此外，内部凹坑4106a和外部凹坑4106b朝向中间凹坑 4106b中的一个的接收半岛部4126延伸。更具体地，内部凹坑4106a与相邻中间凹坑4106b的颈部部分4124对准，并且外部凹坑4106c与相邻中间凹坑4106b的颈部部分4124对准。在某些实例中，凹坑4106的一部分可延伸到相邻凹坑4106的接收半岛部4126中。类似于砧座3900中的凹坑3906，凹坑4106的几何结构便于凹坑4106在钉成形表面4102中的紧密布置。“成形比”是非成形部分4108与成形部分(即，凹坑4106) 的比率。在各种实例中，例如，成形比可以是至少1:1。Referring again to FIG. 44 , each dimple 4106 extends toward the receivingpeninsula 4126 of an adjacent dimple 4106 . For example, themiddle pocket 4106b is aligned with theneck portions 4124 of theinner pocket 4106a andouter pocket 4106c. In addition, theinner pocket 4106a and theouter pocket 4106b extend toward the receivingpeninsula 4126 of one of theintermediate pockets 4106b. More specifically, theinner pocket 4106a is aligned with theneck portion 4124 of the adjacentmiddle pocket 4106b, and theouter pocket 4106c is aligned with theneck portion 4124 of the adjacentmiddle pocket 4106b. In some examples, a portion of a pocket 4106 may extend into the receivingpeninsula 4126 of an adjacent pocket 4106 . Similar to thepockets 3906 in theanvil 3900, the geometry of the pockets 4106 facilitates the close placement of the pockets 4106 in thestaple forming surface 4102. The "forming ratio" is the ratio of theunshaped portion 4108 to the formed portion (ie, the dimples 4106). In various examples, for example, the forming ratio may be at least 1:1.

现在参见图48-51C，示出了砧座4200的一部分中的钉成形凹坑4206。凹坑4206及其在砧座4200中的布置在许多方面类似于凹坑4106及其在砧座4100中的布置。例如，砧座4200包括钉成形表面4202和纵向狭槽 4204。纵向狭槽4204沿砧座4200的纵向轴线LA延伸。在某些实例中，击发元件和/或切割元件可在击发行程的至少一部分期间平移穿过纵向狭槽4204。钉成形凹坑4206限定在钉成形表面4202中。钉成形表面4202 还包括围绕凹坑4206延伸的非成形部分4208。非成形部分4208完全围绕图48中的每个凹坑4206延伸。换句话说，非成形部分4208围绕钉成形凹坑4206。在其他实例中，两个或更多个相邻凹坑4206的至少一部分可邻接接触，使得非成形部分4208不被定位在两者间。Referring now to Figures 48-51C, staple forming pockets 4206 in a portion ofanvil 4200 are shown. The dimples 4206 and their arrangement in theanvil 4200 are similar in many respects to the dimples 4106 and their arrangement in theanvil 4100 . For example, theanvil 4200 includes astaple forming surface 4202 and alongitudinal slot 4204. Thelongitudinal slot 4204 extends along the longitudinal axis LA of theanvil 4200. In certain examples, the firing element and/or cutting element can translate throughlongitudinal slot 4204 during at least a portion of the firing stroke. Staple forming pockets 4206 are defined in thestaple forming surface 4202. Thestaple forming surface 4202 also includes anon-forming portion 4208 extending around the dimples 4206 . Thenon-formed portion 4208 extends completely around each pocket 4206 in FIG. 48 . In other words, thenon-formed portion 4208 forms the pocket 4206 around the staple. In other examples, at least a portion of two or more adjacent pockets 4206 may be in abutting contact such that thenon-shaped portion 4208 is not positioned therebetween.

可优化钉成形表面4202的成形比。通过优化成形比，更多的钉可成形和/或成形为他们期望的构造。在某些实例中，砧座4200的非成形部分4208的表面区域可相对于钉成形凹坑4206被最小化。除此之外或另选地，钉成形凹坑4206的占有面积可延伸或扩大，以最大化钉成形表面 4202的被设计用于捕获和形成钉的部分。The forming ratio of thestaple forming surface 4202 can be optimized. By optimizing the forming ratio, more staples can be formed and/or formed into their desired configuration. In certain examples, the surface area of thenon-forming portion 4208 of theanvil 4200 can be minimized relative to the staple forming pockets 4206. Additionally or alternatively, the footprint of the staple forming pockets 4206 may be extended or enlarged to maximize the portion of thestaple forming surface 4202 designed to capture and form staples.

图48中示出的凹坑4206在纵向狭槽4204的第一侧上被布置成内排 4214a、中间排4214b和外排4214c。内部凹坑4206a被定位在内排4214a 中，中间凹坑4206b被定位在中间排4214b中，并且外部凹坑4206c被定位在外排4214c中。类似于砧座3800，凹坑4206沿砧座4200的钉成形表面4202布置成人字形布置。尽管未在图48中示出，在至少一个实例中，狭槽4204的相对侧上的凹坑4206可形成纵向狭槽4204的第一侧上的凹坑4206的镜像反射。在其他实例中，钉成形表面4202中的凹坑4206的布置可相对于狭槽4204不对称，并且在某些实例中，砧座4200可不包括纵向狭槽4204。在各种实例中，凹坑4206可在狭槽4204的每个侧面上被布置成少于或多于三排。The dimples 4206 shown in Figure 48 are arranged on the first side of thelongitudinal slot 4204 in aninner row 4214a, amiddle row 4214b, and anouter row 4214c. Theinner pockets 4206a are positioned in theinner row 4214a, themiddle pockets 4206b are positioned in themiddle row 4214b, and theouter pockets 4206c are positioned in theouter row 4214c. Similar to theanvil 3800, the pockets 4206 are arranged in a herringbone arrangement along thestaple forming surface 4202 of theanvil 4200. Although not shown in FIG. 48 , in at least one example, the dimples 4206 on opposite sides of theslot 4204 may form mirror reflections of the dimples 4206 on the first side of thelongitudinal slot 4204 . In other examples, the arrangement of the pockets 4206 in thestaple forming surface 4202 may be asymmetrical relative to theslots 4204, and in some examples, theanvil 4200 may not include thelongitudinal slots 4204. In various examples, the dimples 4206 may be arranged in fewer or more than three rows on each side of theslot 4204.

图48中示出的凹坑4206是相同的。限定在钉成形表面4202中的每个凹坑4206具有相同的几何结构。在其他实例中，凹坑4206的几何结构可沿砧座4200的长度逐排和/或纵向地变化。例如，在某些实例中，凹坑4206或其部分的深度可沿砧座4200的长度变化，以适应砧座和钉仓之间的间隙距离沿端部执行器和/或组织流的长度的变化，如本文所述。The dimples 4206 shown in Figure 48 are the same. Each pocket 4206 defined in thestaple forming surface 4202 has the same geometry. In other examples, the geometry of the pockets 4206 may vary row by row and/or longitudinally along the length of theanvil 4200 . For example, in certain instances, the depth of the pocket 4206, or a portion thereof, may vary along the length of theanvil 4200 to accommodate the difference in the gap distance between the anvil and the staple cartridge along the length of the end effector and/or tissue flow. changes, as described herein.

示例性凹坑4206b在图49-51C中示出。凹坑4206b具有第一端部或近侧端部4210和第二端部或远侧端部4212。凹坑轴线PA(图49)在每个凹坑4206的近侧端部4210和远侧端部4212之间延伸。凹坑4206b包括周边4216，周边4216限定凹坑4206b的边界。凹坑4206b还包括近侧杯4220，远侧杯4222，以及连接近侧杯4220和远侧杯4222的颈部部分 4224。当钉被驱动成与钉成形表面4202成形接触时，近侧杯4220与近侧钉腿对准，并且远侧杯4222与远侧钉腿对准。杯4220，4222被构造成能够将钉腿朝向凹坑轴线PA和凹坑4206的中心部分(诸如颈部部分4224) 引导或传送，并使钉腿变形成所成形的构造。Exemplary dimples 4206b are shown in Figures 49-51C. Thedimple 4206b has a first orproximal end 4210 and a second ordistal end 4212. The dimple axis PA ( FIG. 49 ) extends between theproximal end 4210 and thedistal end 4212 of each dimple 4206 . Thedimple 4206b includes aperimeter 4216 that defines the boundary of thedimple 4206b. Thepocket 4206b also includes aproximal cup 4220, adistal cup 4222, and aneck portion 4224 connecting theproximal cup 4220 and thedistal cup 4222. When the staples are driven into forming contact with thestaple forming surfaces 4202, theproximal cups 4220 are aligned with the proximal staple legs and thedistal cups 4222 are aligned with the distal staple legs. Thecups 4220, 4222 are configured to guide or transport the staple legs toward the pocket axis PA and the central portion (such as the neck portion 4224) of the pocket 4206, and deform the staple legs into the shaped configuration.

主要参见图50，凹坑4206b的每个杯4220,4222限定入口斜坡4240 和出口斜坡4242。出口斜坡4242比入口斜坡4240更陡。当形成钉时，钉腿的尖端可沿入口斜坡4240进入相应的杯4220,4222并且沿出口斜坡 4242离开相应的杯4220,4222。在入口斜坡4240和出口斜坡4242之间的顶点4246处，钉腿的尖端朝向钉基部变形以呈现成形的构造，例如诸如B形或修改的B形。凹坑4206b还在近侧杯4220和远侧杯4222之间限定桥接件4244。桥接件4244与非成形部分4208偏置。更具体地，桥接件 4244被定位在非成形部分4208下方或相对于非成形部分4208凹入。Referring primarily to Figure 50, eachcup 4220, 4222 of thepocket 4206b defines aninlet ramp 4240 and anoutlet ramp 4242. Theexit slope 4242 is steeper than theentrance slope 4240. As the staples are formed, the tips of the staple legs can enter therespective cups 4220, 4222 along the inlet ramps 4240 and exit therespective cups 4220, 4222 along the outlet ramps 4242. At the apex 4246 between theinlet ramp 4240 and theoutlet ramp 4242, the tips of the staple legs deform toward the staple base to assume a shaped configuration, such as, for example, a B-shape or a modified B-shape. Thedimple 4206b also defines abridge 4244 between theproximal cup 4220 and thedistal cup 4222.Bridge 4244 is offset fromnon-formed portion 4208. More specifically, thebridges 4244 are positioned below or recessed relative to thenon-shaped portion 4208.

主要参见图51A-51C，凹坑4206b包括侧壁4250，侧壁4250被取向成垂直于钉成形表面4202的非成形部分4208。侧壁4250朝向颈部部分 4224变窄。因此，杯4220,4222的最宽部分位于侧壁4250的近侧端部和远侧端部处。加宽的区域提供用于接收钉腿的尖端的扩大的占有面积。当杯4220,4222朝向颈部部分4224变窄时，杯4220,4222被构造成能够朝向和/或沿凹坑轴线PA传送和/或引导钉腿的尖端并且进入成形构造。Referring primarily to FIGS. 51A-51C , thedimple 4206b includes asidewall 4250 oriented perpendicular to thenon-forming portion 4208 of thestaple forming surface 4202 . Theside wall 4250 narrows towards theneck portion 4224. Thus, the widest portions of thecups 4220 , 4222 are located at the proximal and distal ends of theside wall 4250 . The widened area provides an enlarged footprint for receiving the tips of the staple legs. As thecups 4220, 4222 narrow toward theneck portion 4224, thecups 4220, 4222 are configured to transmit and/or guide the tips of the staple legs toward and/or along the pocket axis PA and into the shaped configuration.

杯4220,4222还分别包括延伸着陆区4230,4232，其进一步扩大了杯 4220,4222的占有面积。近侧延伸着陆区4230沿凹坑轴线PA朝近侧延伸，并且远侧延伸着陆区4232沿凹坑轴线PA朝远侧延伸。在凹坑4206b中，延伸着陆区4230和4232限定基本上三角形的周边。此外，延伸着陆区 4230和4232沿相应的凹坑轴线PA在拐角处终止。在其他实例中，例如，延伸着陆区4230和4232可限定直的或波状周边，并且可从杯4220和4222 侧向和/或纵向延伸。Cups 4220, 4222 also includeextended landing zones 4230, 4232, respectively, which further expand the footprint ofcups 4220, 4222. The proximally extendinglanding zone 4230 extends proximally along the dimple axis PA, and the distally extendinglanding zone 4232 extends distally along the dimple axis PA. Inpocket 4206b,extended landing areas 4230 and 4232 define a substantially triangular perimeter. In addition, theextended landing areas 4230 and 4232 terminate at the corners along the respective dimple axis PA. In other examples, for example,extended landing zones 4230 and 4232 may define a straight or contoured perimeter, and may extend laterally and/or longitudinally fromcups 4220 and 4222.

另外，凹坑4206b在其底表面中包括槽4256。槽4256被构造成能够在钉腿运动到变形构型时约束和引导钉腿。在所示实施方案中，槽4256 跨越在侧壁4250之间并限定凹坑4206b的整个底表面。槽4256从近侧杯 4220延伸越过桥接件4224并进入远侧杯4222。在其他实例中，槽4256 可不延伸跨过凹坑4206b的桥接件4244。槽4256包括两个斜坡表面4256a和4256b，他们向下延伸远离非成形部分4208并沿凹坑形轴线PA相交 (图49)。如图51A-51C所示，槽4256沿桥接件4244限定比在杯4220,4222 中更陡的梯度。在其他实例中，例如，梯度沿槽4256的长度可以是均匀的和/或可在杯4220,4222中比沿桥接件4244更陡。Additionally,dimple 4206b includesgrooves 4256 in its bottom surface. Theslots 4256 are configured to constrain and guide the staple legs as they move to the deformed configuration. In the embodiment shown,grooves 4256 span betweensidewalls 4250 and define the entire bottom surface ofpocket 4206b. Aslot 4256 extends from theproximal cup 4220 over thebridge 4224 and into thedistal cup 4222. In other examples, theslot 4256 may not extend across thebridge 4244 of thedimple 4206b. Thegroove 4256 includes tworamp surfaces 4256a and 4256b that extend downwardly away from thenon-formed portion 4208 and intersect along the dimple-shaped axis PA (FIG. 49). As shown in Figures 51A-51C, thegroove 4256 defines a steeper gradient along thebridge 4244 than in thecups 4220, 4222. In other examples, for example, the gradient may be uniform along the length of thegroove 4256 and/or may be steeper in thecups 4220 , 4222 than along thebridge 4244 .

仍然参见图51A-51C，凹坑4206b还沿凹坑4206b的侧面限定倒角边缘4254。在凹坑4206b中，倒角边缘4254限定凹坑4206b的总宽度。凹坑4206b的总宽度是均匀的。例如，宽度W_A(图51A)等于宽度W_B(图 51B)和宽度W_C(图51C)。在其他实例中，宽度W_A、W_B和/或W_C可不相等。因为侧壁4250朝向颈部部分4224变窄，所以倒角边缘4254的宽度相应地朝向颈部部分4224扩展，以保持相同的总凹坑宽度。凹坑 4206b还包括突起或旋钮4258，突起或旋钮4258在凹坑4206b的颈部部分4224处朝向凹坑轴线PA延伸。旋钮4258进一步使颈部部分4224变窄至宽度W_N。槽4256跨过宽度W_N跨越颈部部分4224的底表面。Still referring to Figures 51A-51C, thedimples 4206b also define chamferededges 4254 along the sides of thedimples 4206b. Inpocket 4206b, chamferededge 4254 defines the overall width ofpocket 4206b. The overall width of thedimples 4206b is uniform. For example, width_WA (FIG. 51A) is equal to width_WB (FIG. 51B) and width_WC (FIG. 51C). In other examples, the widths_WA ,_WB , and/or_WC may not be equal. As thesidewall 4250 narrows toward theneck portion 4224, the width of the chamferededge 4254 correspondingly expands toward theneck portion 4224 to maintain the same overall dimple width. Thepocket 4206b also includes a protrusion orknob 4258 that extends towards the pocket axis PA at theneck portion 4224 of thepocket 4206b.Knob 4258 further narrowsneck portion 4224 to width W_N . Thegroove 4256 spans the bottom surface of theneck portion 4224 across the width W_N.

再次参见图49，凹坑4206b关于凹坑轴线PA对称。例如，凹坑4206b 的周边4216关于凹坑轴线PA对称。此外，凹坑4206b关于穿过颈部部分4224并垂直于凹坑轴线PA的中心轴线CA对称。例如，凹坑4206b 的周边4216关于中心轴线CA对称，并且近侧杯4220具有与远侧杯4222 相同的几何结构。在其他实例中，近侧杯4220可与远侧杯4222不同。例如，再次参见图50，远侧深度D₂可小于近侧深度D₁，以适应砧座和钉仓和/或组织流之间的间隙距离的变化，如本文所述。Referring again to Figure 49, thedimple 4206b is symmetrical about the dimple axis PA. For example, theperimeter 4216 of thedimple 4206b is symmetrical about the dimple axis PA. Furthermore, thedimple 4206b is symmetrical about a central axis CA passing through theneck portion 4224 and perpendicular to the dimple axis PA. For example, theperimeter 4216 of thepocket 4206b is symmetrical about the central axis CA, and theproximal cup 4220 has the same geometry as thedistal cup 4222. In other examples, theproximal cup 4220 can be different from thedistal cup 4222. For example, referring again to Figure 50, the distal depth D2 may be less_than the proximal depth_D1 to accommodate variations in the gap distance between the anvil and the staple cartridge and/or tissue flow, as described herein.

再次参见图48，每个凹坑4206朝向相邻凹坑4206的颈部部分4224 延伸。例如，中间凹坑4206b与内部凹坑4206a和外部凹坑4206c的颈部部分4224对准。更具体地，中间凹坑4206b的近侧着陆区4230与相邻外部钉4206c的颈部部分4224对准，并且中间凹坑4206b的远侧着陆区4232 与相邻内部钉4206a的颈部部分4224对准。此外，内部凹坑4206a和外部凹坑4206b朝向中间凹坑4206b中的一个的颈部部分4224延伸。更具体地，内部凹坑4206a的远侧着陆区4232与相邻中间凹坑4206b的颈部部分4224对准，并且外部凹坑4206c的近侧着陆区4230与相邻中间凹坑 4206b的颈部部分4224对准。Referring again to FIG. 48 , each dimple 4206 extends toward theneck portion 4224 of an adjacent dimple 4206 . For example, themiddle pocket 4206b is aligned with theneck portions 4224 of theinner pocket 4206a andouter pocket 4206c. More specifically, theproximal landing zone 4230 of themiddle pocket 4206b is aligned with theneck portion 4224 of the adjacent outer staple 4206c, and thedistal landing zone 4232 of themiddle pocket 4206b is aligned with theneck portion 4224 of the adjacentinner staple 4206a alignment. Additionally, theinner pocket 4206a and theouter pocket 4206b extend toward theneck portion 4224 of one of theintermediate pockets 4206b. More specifically, thedistal landing zone 4232 of theinner pocket 4206a is aligned with theneck portion 4224 of the adjacentintermediate pocket 4206b, and theproximal landing zone 4230 of theouter pocket 4206c is aligned with the neck portion of the adjacentintermediate pocket 4206b.Section 4224 is aligned.

现在参见图52-55C，示出了砧座4300的一部分中的钉成形凹坑4306。凹坑4306及其在砧座4300中的布置在许多方面类似于凹坑3906及其在砧座3900中的布置。例如，砧座4300包括钉成形表面4302和纵向狭槽 4304。纵向狭槽4304沿砧座4300的纵向轴线LA延伸。在某些实例中，击发元件和/或切割元件可在击发行程的至少一部分期间平移穿过纵向狭槽4304。钉成形凹坑4306限定在钉成形表面4302中。钉成形表面4302 还包括围绕凹坑4306延伸的非成形部分4308。非成形部分4308完全围绕图52中的每个凹坑4306延伸。换句话说，非成形部分4308围绕钉成形凹坑4306。在其他实例中，两个或更多个相邻凹坑4306的至少一部分可邻接接触，使得非成形部分4308不被定位在两者间。Referring now to Figures 52-55C, staple forming pockets 4306 in a portion ofanvil 4300 are shown. The pockets 4306 and their arrangement in theanvil 4300 are similar in many respects to thepockets 3906 and their arrangement in theanvil 3900 . For example, theanvil 4300 includes astaple forming surface 4302 and alongitudinal slot 4304. Thelongitudinal slot 4304 extends along the longitudinal axis LA of theanvil 4300. In certain examples, the firing element and/or cutting element can translate throughlongitudinal slot 4304 during at least a portion of the firing stroke. Staple forming pockets 4306 are defined in thestaple forming surface 4302. Thestaple forming surface 4302 also includes anon-forming portion 4308 extending around the dimples 4306 . Thenon-formed portion 4308 extends completely around each pocket 4306 in FIG. 52 . In other words, thenon-formed portion 4308 forms the pocket 4306 around the staple. In other examples, at least a portion of two or more adjacent pockets 4306 may be in abutting contact such that thenon-shaped portion 4308 is not positioned therebetween.

可优化钉成形表面4302的成形比。通过优化成形比，更多的钉可成形和/或成形为他们期望的构造。在某些实例中，砧座4300的非成形部分4308的表面区域可相对于钉成形凹坑4306被最小化。除此之外或另选地，钉成形凹坑4306的占有面积可延伸或扩大，以最大化钉成形表面 4302的被设计用于捕获和形成钉的部分。The forming ratio of thestaple forming surface 4302 can be optimized. By optimizing the forming ratio, more staples can be formed and/or formed into their desired configuration. In certain examples, the surface area of thenon-forming portion 4308 of theanvil 4300 can be minimized relative to the staple forming pockets 4306. Additionally or alternatively, the footprint of the staple forming pockets 4306 may be extended or enlarged to maximize the portion of thestaple forming surface 4302 designed to capture and form staples.

图52中示出的凹坑4306在纵向狭槽4304的第一侧上被布置成内排 4314a、中间排4314b和外排4314c。内部凹坑4306a被定位在内排4314a 中，中间凹坑4306b被定位在中间排4314b中，并且外部凹坑4306c被定位在外排4314c中。类似于砧座3800，凹坑4306沿砧座4300的钉成形表面4302布置成人字形布置。尽管未在图52中示出，在至少一个实例中，狭槽4304的相对侧上的凹坑4306可形成纵向狭槽4304的第一侧上的凹坑4306的镜像反射。在其他实例中，钉成形表面4302中的凹坑4306的布置可相对于狭槽4304不对称，并且在某些实例中，砧座4300可不包括纵向狭槽4304。在各种实例中，凹坑4306可在狭槽4304的每个侧面上被布置成少于或多于三排。The dimples 4306 shown in Figure 52 are arranged on the first side of thelongitudinal slot 4304 in aninner row 4314a, amiddle row 4314b, and anouter row 4314c. Theinner pockets 4306a are positioned in theinner row 4314a, themiddle pockets 4306b are positioned in themiddle row 4314b, and theouter pockets 4306c are positioned in theouter row 4314c. Similar to theanvil 3800, the pockets 4306 are arranged in a herringbone arrangement along thestaple forming surface 4302 of theanvil 4300. Although not shown in FIG. 52 , in at least one example, the dimples 4306 on opposite sides of theslot 4304 may form mirror reflections of the dimples 4306 on the first side of thelongitudinal slot 4304 . In other examples, the arrangement of the pockets 4306 in thestaple forming surface 4302 may be asymmetric relative to theslots 4304, and in some examples, theanvil 4300 may not include thelongitudinal slots 4304. In various examples, the dimples 4306 may be arranged in fewer or more than three rows on each side of theslot 4304.

图52中示出的凹坑4306是相同的。限定在钉成形表面4302中的每个凹坑4306具有相同的几何结构。在其他实例中，凹坑4306的几何结构可沿砧座4300的长度逐排和/或纵向地变化。例如，在某些实例中，凹坑4306或其部分的深度可沿砧座4300的长度变化，以适应砧座和钉仓之间的间隙距离沿端部执行器和/或组织流的长度的变化，如本文所述。The dimples 4306 shown in Figure 52 are the same. Each pocket 4306 defined in thestaple forming surface 4302 has the same geometry. In other examples, the geometry of the pockets 4306 may vary row by row and/or longitudinally along the length of theanvil 4300 . For example, in certain instances, the depth of the pockets 4306 or portions thereof may vary along the length of theanvil 4300 to accommodate the change in the gap distance between the anvil and the staple cartridge along the length of the end effector and/or tissue flow changes, as described herein.

示例性凹坑4306b在图53-55C中示出。凹坑4306b具有第一端部或近侧端部4310和第二端部或远侧端部4312。凹坑轴线PA(图53)在凹坑4306b的近侧端部4310和远侧端部4312之间延伸。凹坑4306b包括周边4316，周边4316限定凹坑4306b的边界。周边4316包括在凹坑4306 的近侧端部和远侧端部处的圆角。凹坑4306b还包括近侧杯4320，远侧杯4322，以及连接近侧杯4320和远侧杯4322的颈部部分4324。当钉被驱动成与钉成形表面4302成形接触时，近侧杯4320与近侧钉腿对准，并且远侧杯4322与远侧钉腿对准。杯4320，4322被构造成能够将钉腿朝向凹坑轴线PA和凹坑4306的中心部分(诸如颈部部分4324)引导或传送，并使钉腿变形成所成形的构造。Exemplary dimples 4306b are shown in Figures 53-55C. Thedimple 4306b has a first orproximal end 4310 and a second ordistal end 4312. The dimple axis PA (FIG. 53) extends between theproximal end 4310 and thedistal end 4312 of thedimple 4306b. Thedimple 4306b includes aperimeter 4316 that defines the boundary of thedimple 4306b. Theperimeter 4316 includes rounded corners at the proximal and distal ends of the pocket 4306 . Thepocket 4306b also includes aproximal cup 4320, adistal cup 4322, and aneck portion 4324 connecting theproximal cup 4320 and thedistal cup 4322. When the staples are driven into forming contact with thestaple forming surfaces 4302, theproximal cups 4320 are aligned with the proximal staple legs and thedistal cups 4322 are aligned with the distal staple legs. Thecups 4320, 4322 are configured to guide or transport the staple legs toward the pocket axis PA and the central portion of the pocket 4306, such as theneck portion 4324, and deform the staple legs into the shaped configuration.

主要参见图54，凹坑4306b的每个杯4320,4322限定入口斜坡4340 和出口斜坡4342。出口斜坡4342比入口斜坡4340更陡。当形成钉时，钉腿的尖端可沿入口斜坡4340进入相应的杯4320,4322并且沿出口斜坡 4342离开相应的杯4320,4322。在入口斜坡4340和出口斜坡4342之间的顶点4346处，钉腿的尖端朝向钉基部变形以呈现成形的构造，例如诸如B形或修改的B形。凹坑4306b还在近侧杯4320和远侧杯4322之间限定桥接件4344。桥接件4344与非成形部分4308偏置。更具体地，桥接件 4344被定位在非成形部分4308下方或相对于非成形部分4308凹入。Referring primarily to FIG. 54, eachcup 4320, 4322 of thepocket 4306b defines aninlet ramp 4340 and anoutlet ramp 4342. Theexit slope 4342 is steeper than theentrance slope 4340. When the staples are formed, the tips of the staple legs can enter therespective cups 4320, 4322 along the inlet ramps 4340 and exit therespective cups 4320, 4322 along the outlet ramps 4342. At apex 4346 betweeninlet ramp 4340 andoutlet ramp 4342, the tips of the staple legs deform toward the staple base to assume a shaped configuration, such as a B-shape or a modified B-shape, for example. Thedimple 4306b also defines abridge 4344 between theproximal cup 4320 and thedistal cup 4322.Bridge 4344 is offset fromnon-formed portion 4308. More specifically, thebridges 4344 are positioned below or recessed relative to thenon-shaped portion 4308.

主要参见图55A-55C，凹坑4306b包括侧壁4350，侧壁4350被取向成垂直于钉成形表面4302的非成形部分4308。侧壁4350在每个杯4320, 4322的外端和颈部部分4324之间变窄。更具体地，侧壁4350沿向内轮廓延伸，以在凹坑4306b的周边4316中限定轮廓。杯4320,4322的最宽部分位于侧壁4350的近侧端部和远侧端部处。加宽的区域提供用于接收钉腿的尖端的扩大的占有面积。当杯4320,4322朝向颈部部分4324变窄时，杯4320,4322被构造成能够朝向和/或沿凹坑轴线PA传送和/或引导钉腿的尖端并且进入成形构造。Referring primarily to FIGS. 55A-55C , thepocket 4306b includes asidewall 4350 oriented perpendicular to thenon-forming portion 4308 of thestaple forming surface 4302. Theside wall 4350 narrows between the outer end of eachcup 4320, 4322 and theneck portion 4324. More specifically, thesidewall 4350 extends along an inward profile to define a profile in theperimeter 4316 of thepocket 4306b. The widest portions of thecups 4320 , 4322 are located at the proximal and distal ends of theside wall 4350 . The widened area provides an enlarged footprint for receiving the tips of the staple legs. As thecups 4320, 4322 narrow toward theneck portion 4324, thecups 4320, 4322 are configured to transmit and/or guide the tips of the staple legs toward and/or along the pocket axis PA and into the shaped configuration.

凹坑4306b沿凹坑4306b的侧面限定倒角边缘4354。在凹坑4306b 中，倒角边缘4354限定凹坑4306b的总宽度，其朝向颈部部分4324变窄。凹坑4306b还在凹坑4306b的侧壁4350和底表面4358之间限定圆角4352 (图55A-55C)。圆角4352被构造成能够沿凹坑4306b中的期望路径引导钉腿。例如，如果钉腿沿倒角4352着陆，则圆角4352可平滑地引导钉腿朝向凹坑轴线PA。Thedimple 4306b defines a chamferededge 4354 along the sides of thedimple 4306b. Inpocket 4306b, chamferededge 4354 defines the overall width ofpocket 4306b, which narrows towardneck portion 4324. Thedimple 4306b also defines afillet 4352 between thesidewall 4350 and thebottom surface 4358 of thedimple 4306b (FIGS. 55A-55C). Thefillets 4352 are configured to guide the staple legs along a desired path in thepockets 4306b. For example, if the staple legs land along thechamfer 4352, thefillet 4352 may smoothly guide the staple legs toward the pocket axis PA.

再次参见图53，凹坑4306b关于凹坑轴线PA对称。例如，凹坑4306b 的周边4316关于凹坑轴线PA对称。此外，凹坑4306b关于穿过颈部部分4324并垂直于凹坑轴线PA的中心轴线CA对称。例如，凹坑4306b 的周边4316关于中心轴线CA对称，并且近侧杯4320具有与远侧杯4322 相同的几何结构。在其他实例中，近侧杯4320可与远侧杯4322不同。例如，再次参见图54，远侧深度D₂可小于近侧深度D₁，以适应砧座和钉仓和/或组织流之间的间隙距离的变化，如本文所述。Referring again to Figure 53, thedimple 4306b is symmetrical about the dimple axis PA. For example, theperimeter 4316 of thedimple 4306b is symmetrical about the dimple axis PA. Furthermore, thedimple 4306b is symmetrical about a central axis CA passing through theneck portion 4324 and perpendicular to the dimple axis PA. For example, theperimeter 4316 of thepocket 4306b is symmetrical about the central axis CA, and theproximal cup 4320 has the same geometry as thedistal cup 4322. In other examples, theproximal cup 4320 can be different from thedistal cup 4322. For example, referring again to Figure 54, the distal depth D2 may be less_than the proximal depth_D1 to accommodate variations in the gap distance between the anvil and the staple cartridge and/or tissue flow, as described herein.

再次参见图53，凹坑4306b的颈部部分4324比近侧杯4320和远侧杯4322窄。凹坑4306b的变窄的周边4316在近侧杯4320的一部分和远侧杯4322的一部分之间限定接收半岛部4326。由于凹坑4306b的对称性，对称的接收半岛部4326被定位在凹坑4306b的每个侧面上。接收半岛部 4326由凹坑4306b的周边4316和切线轴线(例如，T_B1和T_B2)界定，该切线轴线与凹坑4306b的侧面上的近侧杯4320和远侧杯4322的最宽部分相切。第一切线轴线T_B1被定位在凹坑4306b的第一侧上，并且第二切线轴线T_B2被定位在凹坑4306b的相对侧上。图53中示出的第一切线轴线 T_B1和第二切线轴线T_B2与凹坑轴线PA平行。Referring again to FIG. 53, theneck portion 4324 of thepocket 4306b is narrower than theproximal cup 4320 and thedistal cup 4322. The narrowedperimeter 4316 of thepocket 4306b defines a receivingpeninsula 4326 between a portion of theproximal cup 4320 and a portion of thedistal cup 4322. Due to the symmetry of thepocket 4306b,symmetrical receiving peninsulas 4326 are positioned on each side of thepocket 4306b. The receivingpeninsula 4326 is bounded by theperimeter 4316 of thepocket 4306b and a tangential axis (eg, T_B1 and T_B2 ) that is opposite the widest portions of the proximal anddistal cups 4320 and 4322 on the sides of thepocket 4306b cut. The first tangential axis TB1 is positioned on a first side of the pocket_4306b , and the second tangential axis_TB2 is positioned on the opposite side of thepocket 4306b. The first tangential axis_TB1 and the second tangential axis_TB2 shown in FIG. 53 are parallel to the pit axis PA.

再次参见图52，每个凹坑4306朝向相邻凹坑4306的接收半岛部4326 延伸。例如，中间凹坑4306b与内部凹坑4306a和外部凹坑4306c的颈部部分4324对准。此外，内部凹坑4306a和外部凹坑4306b朝向中间凹坑 4306b中的一个的接收半岛部4326延伸。更具体地，内部凹坑4306a与相邻中间凹坑4306b的颈部部分4324对准，并且外部凹坑4306c与相邻中间凹坑4306b的颈部部分4324对准。在某些实例中，凹坑4306的一部分可延伸到相邻凹坑4306的接收半岛部4326中。类似于砧座3900中的凹坑3906，凹坑4306的几何结构便于凹坑4306在钉成形表面4302中的紧密布置。“成形比”是非成形部分4308与成形部分(即，凹坑4306) 的比率。在至少一个实例中，例如，成形比可以是至少1:1。Referring again to FIG. 52 , each dimple 4306 extends toward the receivingpeninsula 4326 of an adjacent dimple 4306 . For example, themiddle pocket 4306b is aligned with theneck portions 4324 of theinner pocket 4306a andouter pocket 4306c. Additionally, theinner pocket 4306a and theouter pocket 4306b extend toward the receivingpeninsula 4326 of one of theintermediate pockets 4306b. More specifically, theinner pocket 4306a is aligned with theneck portion 4324 of the adjacentmiddle pocket 4306b, and theouter pocket 4306c is aligned with theneck portion 4324 of the adjacentmiddle pocket 4306b. In some examples, a portion of a pocket 4306 may extend into the receivingpeninsula 4326 of an adjacent pocket 4306 . Similar to thepockets 3906 in theanvil 3900, the geometry of the pockets 4306 facilitates the close placement of the pockets 4306 in thestaple forming surface 4302. The "forming ratio" is the ratio of theunshaped portion 4308 to the formed portion (ie, the dimples 4306). In at least one example, for example, the forming ratio can be at least 1:1.

现在参见图56-59C，示出了砧座4400的一部分中的钉成形凹坑4406。凹坑4406及其在砧座4400中的布置在许多方面类似于凹坑4306及其在砧座4300中的布置。例如，砧座4400包括钉成形表面4402和纵向狭槽 4404。纵向狭槽4404沿砧座4400的纵向轴线LA延伸。在某些实例中，击发元件和/或切割元件可在击发行程的至少一部分期间平移穿过纵向狭槽4404。钉成形凹坑4406限定在钉成形表面4402中。钉成形表面4402 还包括围绕凹坑4406延伸的非成形部分4408。非成形部分4408完全围绕图56中的每个凹坑4406延伸。换句话说，非成形部分4408围绕钉成形凹坑4406。在其他实例中，两个或更多个相邻凹坑4406的至少一部分可邻接接触，使得非成形部分4408不被定位在两者间。另外，非成形部分4406延伸穿过每个凹坑4406，如本文所述。Referring now to Figures 56-59C,staple forming pockets 4406 in a portion ofanvil 4400 are shown. Thedimples 4406 and their arrangement in theanvil 4400 are similar in many respects to the dimples 4306 and their arrangement in theanvil 4300 . For example, theanvil 4400 includes astaple forming surface 4402 and alongitudinal slot 4404. Thelongitudinal slot 4404 extends along the longitudinal axis LA of theanvil 4400 . In certain examples, the firing element and/or cutting element can translate throughlongitudinal slot 4404 during at least a portion of the firing stroke.Staple forming pockets 4406 are defined in thestaple forming surface 4402. Thestaple forming surface 4402 also includes anon-forming portion 4408 extending around thedimples 4406 . Thenon-formed portion 4408 extends completely around eachpocket 4406 in FIG. 56 . In other words, thenon-formed portion 4408 forms thepocket 4406 around the staple. In other examples, at least a portion of two or moreadjacent pockets 4406 may be in abutting contact such that thenon-shaped portion 4408 is not positioned therebetween. Additionally, anon-formed portion 4406 extends through eachpocket 4406, as described herein.

可优化钉成形表面4402的成形比。通过优化成形比，更多的钉可成形和/或成形为他们期望的构造。在某些实例中，砧座4400的非成形部分4408的表面区域可相对于钉成形凹坑4406被最小化。除此之外或另选地，钉成形凹坑4406的占有面积可延伸或扩大，以最大化钉成形表面 4402的被设计用于捕获和形成钉的部分。The forming ratio of thestaple forming surface 4402 can be optimized. By optimizing the forming ratio, more staples can be formed and/or formed into their desired configuration. In certain examples, the surface area of thenon-forming portion 4408 of theanvil 4400 can be minimized relative to thestaple forming pockets 4406. Additionally or alternatively, the footprint of thestaple forming pockets 4406 may be extended or enlarged to maximize the portion of thestaple forming surface 4402 designed to capture and form staples.

图56中示出的凹坑4406在纵向狭槽4404的第一侧上被布置成内排 4414a、中间排4414b和外排4414c。内部凹坑4406a被定位在内排4414a 中，中间凹坑4406b被定位在中间排4414b中，并且外部凹坑4406c被定位在外排4414c中。类似于砧座3800，凹坑4406沿砧座4400的钉成形表面4402布置成人字形布置。尽管未在图56中示出，在至少一个实例中，狭槽4404的相对侧上的凹坑4406可形成纵向狭槽4404的第一侧上的凹坑4406的镜像反射。在其他实例中，钉成形表面4402中的凹坑4406的布置可相对于狭槽4404不对称，并且在某些实例中，砧座4400可不包括纵向狭槽4404。在各种实例中，凹坑4406可在狭槽4404的每个侧面上被布置成少于或多于三排。Thedimples 4406 shown in Figure 56 are arranged on the first side of thelongitudinal slot 4404 in aninner row 4414a, amiddle row 4414b and anouter row 4414c. Theinner pockets 4406a are positioned in theinner row 4414a, themiddle pockets 4406b are positioned in themiddle row 4414b, and the outer pockets 4406c are positioned in theouter row 4414c. Similar to theanvil 3800, thepockets 4406 are arranged in a herringbone arrangement along thestaple forming surface 4402 of theanvil 4400. Although not shown in FIG. 56 , in at least one example, thedimples 4406 on opposite sides of theslot 4404 may form mirror reflections of thedimples 4406 on the first side of thelongitudinal slot 4404 . In other examples, the arrangement of thepockets 4406 in thestaple forming surface 4402 may be asymmetric relative to theslots 4404, and in some examples, theanvil 4400 may not include thelongitudinal slots 4404. In various examples, thedimples 4406 may be arranged in fewer or more than three rows on each side of theslot 4404 .

图56中示出的凹坑4406是相同的。限定在钉成形表面4402中的每个凹坑4406具有相同的几何结构。在其他实例中，凹坑4406的几何结构可沿砧座4400的长度逐排和/或纵向地变化。例如，在某些实例中，凹坑4406或其部分的深度可沿砧座4400的长度变化，以适应砧座和钉仓之间的间隙距离沿端部执行器和/或组织流的长度的变化，如本文所述。Thedimples 4406 shown in Figure 56 are the same. Eachpocket 4406 defined in thestaple forming surface 4402 has the same geometry. In other examples, the geometry of thepockets 4406 may vary row by row and/or longitudinally along the length of theanvil 4400 . For example, in certain instances, the depth of thepocket 4406, or a portion thereof, may vary along the length of theanvil 4400 to accommodate the variation of the gap distance between the anvil and the staple cartridge along the length of the end effector and/or tissue flow changes, as described herein.

示例性凹坑4406b在图57-59C中示出。凹坑4406b具有第一端部或近侧端部4410和第二端部或远侧端部4412。凹坑轴线PA(图57)在凹坑4406b的近侧端部4410和远侧端部4412之间延伸。凹坑4406b包括周边4416，周边4416限定凹坑4406b的边界。周边4416包括在凹坑4406b 的近侧端部4410和远侧端部4412处的圆角。凹坑4406b还包括近侧杯 4420和远侧杯4422。非成形部分4408的一部分在近侧杯4420和远侧杯 4422之间延伸。换句话说，凹坑4406b包括在钉成形表面4402中的两个单独且分立的杯4420和4422。当钉被驱动成与钉成形表面4402成形接触时，近侧杯4420与近侧钉腿对准，并且远侧杯4422与远侧钉腿对准。杯4420，4422被构造成能够将钉腿朝向凹坑轴线PA和凹坑4406的中心部分引导或传送，并使钉腿变形成所成形的构造。Exemplary dimples 4406b are shown in Figures 57-59C. Thedimple 4406b has a first orproximal end 4410 and a second ordistal end 4412. The dimple axis PA (FIG. 57) extends between theproximal end 4410 and thedistal end 4412 of thedimple 4406b. Thedimple 4406b includes a perimeter 4416 that defines the boundary of thedimple 4406b. The perimeter 4416 includes rounded corners at theproximal end 4410 and thedistal end 4412 of thepocket 4406b. Thepocket 4406b also includes aproximal cup 4420 and adistal cup 4422. A portion of thenon-shaped portion 4408 extends between theproximal cup 4420 and thedistal cup 4422. In other words, thepocket 4406b includes two separate anddiscrete cups 4420 and 4422 in thestaple forming surface 4402. When the staples are driven into forming contact with thestaple forming surfaces 4402, theproximal cups 4420 are aligned with the proximal staple legs and thedistal cups 4422 are aligned with the distal staple legs. Thecups 4420, 4422 are configured to guide or transport the staple legs toward the pocket axis PA and the central portion of thepocket 4406 and deform the staple legs into the shaped configuration.

主要参见图58，凹坑4406b的每个杯4420,4422限定入口斜坡4440 和出口斜坡4442。出口斜坡4442比入口斜坡4440更陡。当形成钉时，钉腿的尖端可沿入口斜坡4440进入相应的杯4420,4422并且沿出口斜坡 4442离开相应的杯4420,4422。在入口斜坡4440和出口斜坡4442之间的顶点4446处，钉腿的尖端朝向钉基部变形以呈现成形的构造，例如诸如B形或修改的B形。凹坑4406b还在近侧杯4420和远侧杯4422之间限定桥接件4444。桥接件4444与非成形部分4408对准。更具体地，桥接件4444是非成形部分4408的平面延伸部，其在近侧杯4420和远侧杯4422 之间延伸。Referring primarily to Figure 58, eachcup 4420, 4422 of thepocket 4406b defines aninlet ramp 4440 and anoutlet ramp 4442. Theexit slope 4442 is steeper than theentrance slope 4440. As the staples are formed, the tips of the staple legs can enter therespective cups 4420, 4422 along the inlet ramps 4440 and exit therespective cups 4420, 4422 along the outlet ramps 4442. At the apex 4446 between theinlet ramp 4440 and theoutlet ramp 4442, the tips of the staple legs deform toward the staple base to assume a shaped configuration, such as a B-shape or a modified B-shape, for example. Thepocket 4406b also defines abridge 4444 between theproximal cup 4420 and thedistal cup 4422.Bridge 4444 is aligned withnon-formed portion 4408. More specifically,bridge 4444 is a planar extension ofnon-formed portion 4408 that extends betweenproximal cup 4420 anddistal cup 4422.

主要参见图59A-59C，凹坑4406b包括侧壁4450，侧壁4450相对于钉成形表面4402的非成形部分4408以一定角度取向。更具体地，侧壁 4450相对于非成形部分4408倾斜地取向。此外，侧壁4450的角度取向沿杯的长度是恒定的。例如，分别在图59A、图59B和图59C中示出的角度A、B和C相等。在其他实例中，角度A、B和C中的一个或多个可以是不同的。侧壁4450在每个杯4420,4422的外端和杯4420,4422的内端之间变窄。更具体地，侧壁4450沿向内轮廓延伸，以在凹坑4406b的周边4416中限定轮廓。杯4420,4422的最宽部分位于凹坑4406b的近侧端部和远侧端部处。加宽的区域提供用于接收钉腿的尖端的扩大的占有面积。当杯4420,4422朝向桥接件4444变窄时，杯4420,4422被构造成能够朝向和/或沿凹坑轴线PA传送和/或引导钉腿的尖端并且进入成形构造。59A-59C, thepocket 4406b includes aside wall 4450 oriented at an angle relative to thenon-forming portion 4408 of thestaple forming surface 4402. More specifically, thesidewalls 4450 are oriented obliquely with respect to thenon-formed portion 4408. Furthermore, the angular orientation of theside walls 4450 is constant along the length of the cup. For example, angles A, B, and C shown in Figures 59A, 59B, and 59C, respectively, are equal. In other instances, one or more of angles A, B, and C may be different. Theside wall 4450 narrows between the outer end of eachcup 4420, 4422 and the inner end of thecups 4420, 4422. More specifically, thesidewall 4450 extends along an inward profile to define a profile in the perimeter 4416 of thepocket 4406b. The widest portions of thecups 4420, 4422 are located at the proximal and distal ends of thepocket 4406b. The widened area provides an enlarged footprint for receiving the tips of the staple legs. As thecups 4420, 4422 narrow toward thebridge 4444, thecups 4420, 4422 are configured to transmit and/or guide the tips of the staple legs toward and/or along the pocket axis PA and into the shaped configuration.

凹坑4406b在凹坑4406b的侧壁4450和底表面4458之间限定圆角 4452(图59A-59C)。圆角4452被构造成能够沿凹坑4406b中的期望路径引导钉腿。例如，如果钉腿沿圆角4452着陆，则圆角4452可平滑地引导钉腿朝向凹坑轴线PA。Thedimple 4406b defines afillet 4452 between thesidewall 4450 and thebottom surface 4458 of thedimple 4406b (FIGS. 59A-59C). Thefillets 4452 are configured to guide the staple legs along a desired path in thepockets 4406b. For example, if the staple legs land along thefillet 4452, thefillet 4452 may smoothly guide the staple legs toward the pocket axis PA.

再次参见图57，凹坑4406b关于凹坑轴线PA对称。例如，凹坑4406b 的周边4416关于凹坑轴线PA对称。此外，凹坑4406b关于近侧杯4420 和远侧杯4422之间的并且垂直于凹坑轴线PA的中心轴线CA对称。例如，凹坑4406b的周边4416关于中心轴线CA对称，并且近侧杯4420具有与远侧杯4422相同的几何结构。在其他实例中，近侧杯4420可与远侧杯4422不同。例如，再次参见图58，远侧深度D₂可小于近侧深度D₁，以适应砧座和钉仓和/或组织流之间的间隙距离的变化，如本文所述。Referring again to Figure 57, thedimple 4406b is symmetrical about the dimple axis PA. For example, the perimeter 4416 of thedimple 4406b is symmetrical about the dimple axis PA. Furthermore, thedimple 4406b is symmetrical about a central axis CA between theproximal cup 4420 and thedistal cup 4422 and perpendicular to the dimple axis PA. For example, the perimeter 4416 of thepocket 4406b is symmetrical about the central axis CA, and theproximal cup 4420 has the same geometry as thedistal cup 4422. In other examples, theproximal cup 4420 can be different from thedistal cup 4422. For example, referring again to Figure 58, the distal depth D2 may be less_than the proximal depth_D1 to accommodate variations in the gap distance between the anvil and the staple cartridge and/or tissue flow, as described herein.

再次参见图57，凹坑4406b的中心部分分别比杯4420和4422的近侧端部4410和远侧端部4412窄。凹坑4406b的变窄的周边4416在近侧杯4420的一部分和远侧杯4422的一部分之间限定接收半岛部4426。由于凹坑4406b的对称性，对称的接收半岛部4426被定位在凹坑4406b的每个侧面上。接收半岛部4426由凹坑4406b的周边4416和切线轴线(例如，T_B1和T_B2)界定，该切线轴线与凹坑4406b的侧面上的近侧杯4420 和远侧杯4422的最宽部分相切。第一切线轴线T_B1被定位在凹坑4406b 的第一侧上，并且第二切线轴线T_B2被定位在凹坑4406b的相对侧上。图 57中示出的第一切线轴线T_B1和第二切线轴线T_B2与凹坑轴线PA平行。Referring again to Figure 57, the central portion of thepocket 4406b is narrower than theproximal end 4410 and thedistal end 4412 of thecups 4420 and 4422, respectively. The narrowed perimeter 4416 of thepocket 4406b defines a receivingpeninsula 4426 between a portion of theproximal cup 4420 and a portion of thedistal cup 4422. Due to the symmetry of thepocket 4406b,symmetrical receiving peninsulas 4426 are positioned on each side of thepocket 4406b. The receivingpeninsula 4426 is bounded by the perimeter 4416 of thepocket 4406b and a tangential axis (eg, T_B1 and T_B2 ) that is aligned with the widest portions of the proximal anddistal cups 4420 and 4422 on the sides of thepocket 4406b. cut. The first tangential axis TB1 is positioned on a first side of the pocket_4406b , and the second tangential axis_TB2 is positioned on the opposite side of thepocket 4406b. The first and second tangential axes_TB1 and_TB2 shown in FIG. 57 are parallel to the pit axis PA.

再次参见图56，每个凹坑4406朝向相邻凹坑4406的接收半岛部4426 延伸。例如，中间凹坑4406b与内部凹坑4406a和外部凹坑4406c的中心部分对准。此外，内部凹坑4406a和外部凹坑4406b朝向中间凹坑4406b 中的一个的接收半岛部4426延伸。更具体地，内部凹坑4406a与相邻中间凹坑4406b的中心部分对准，并且外部凹坑4406c与相邻中间凹坑4406b的中心部分对准。在某些实例中，凹坑4406的一部分可延伸到相邻凹坑4406的接收半岛部4426中。类似于砧座3900中的凹坑3906，凹坑4406的几何结构便于凹坑4406在钉成形表面4402中的紧密布置。钉成形表面4402的“成形比”是非成形部分4408与成形部分(即，凹坑 4406)的比率。钉成形表面4402的成形比为约2.56:1。在其他实例中，成形比可小于2.56:1或大于2.56:1。例如，在至少一个实例中，钉成形表面4402的50％以上可用钉成形凹坑4406覆盖。Referring again to FIG. 56 , eachdimple 4406 extends toward the receivingpeninsula 4426 of anadjacent dimple 4406 . For example, themiddle dimple 4406b is aligned with the central portion of theinner dimple 4406a and outer dimple 4406c. Additionally, theinner pocket 4406a and theouter pocket 4406b extend toward the receivingpeninsula 4426 of one of theintermediate pockets 4406b. More specifically, theinner pocket 4406a is aligned with the central portion of the adjacentmiddle pocket 4406b, and the outer pocket 4406c is aligned with the central portion of the adjacentmiddle pocket 4406b. In some examples, a portion of adimple 4406 may extend into the receivingpeninsula 4426 of anadjacent dimple 4406 . Similar to thepockets 3906 in theanvil 3900, the geometry of thepockets 4406 facilitates the close placement of thepockets 4406 in thestaple forming surface 4402. The "formation ratio" of thestaple forming surface 4402 is the ratio of thenon-formed portion 4408 to the formed portion (i.e., the dimples 4406). The forming ratio of thestaple forming surface 4402 is about 2.56:1. In other examples, the forming ratio may be less than 2.56:1 or greater than 2.56:1. For example, in at least one example, more than 50% of thestaple forming surface 4402 can be covered with thestaple forming pockets 4406.

现在参见图60-63C，示出了砧座4500的一部分中的钉成形凹坑4506。凹坑4506及其在砧座4500中的布置在许多方面类似于凹坑3906及其在砧座3900中的布置。例如，砧座4500包括钉成形表面4502和纵向狭槽 4504。纵向狭槽4504沿砧座4500的纵向轴线LA延伸。在某些实例中，击发元件和/或切割元件可在击发行程的至少一部分期间平移穿过纵向狭槽4504。钉成形凹坑4506限定在钉成形表面4502中。钉成形表面4502 还包括围绕凹坑4506延伸的非成形部分4508。非成形部分4508完全围绕图60中的每个凹坑4506延伸。换句话说，非成形部分4508围绕钉成形凹坑4506。在其他实例中，两个或更多个相邻凹坑4506的至少一部分可邻接接触，使得非成形部分4508不被定位在两者间。Referring now to Figures 60-63C,staple forming pockets 4506 in a portion ofanvil 4500 are shown. Thedimples 4506 and their arrangement in theanvil 4500 are similar in many respects to thedimples 3906 and their arrangement in theanvil 3900 . For example, theanvil 4500 includes astaple forming surface 4502 and alongitudinal slot 4504. Thelongitudinal slot 4504 extends along the longitudinal axis LA of theanvil 4500. In certain examples, the firing element and/or cutting element can translate throughlongitudinal slot 4504 during at least a portion of the firing stroke.Staple forming pockets 4506 are defined in thestaple forming surface 4502. Thestaple forming surface 4502 also includes anon-forming portion 4508 extending around thepockets 4506. Thenon-formed portion 4508 extends completely around eachpocket 4506 in FIG. 60 . In other words, thenon-formed portion 4508 forms thepocket 4506 around the staple. In other examples, at least a portion of two or moreadjacent pockets 4506 may be in abutting contact such that thenon-shaped portion 4508 is not positioned therebetween.

可优化钉成形表面4502的成形比。通过优化成形比，更多的钉可成形和/或成形为他们期望的构造。在某些实例中，砧座4500的非成形部分4508的表面区域可相对于钉成形凹坑4506被最小化。除此之外或另选地，钉成形凹坑4506的占有面积可延伸或扩大，以最大化钉成形表面 4502的被设计用于捕获和形成钉的部分。The forming ratio of thestaple forming surface 4502 can be optimized. By optimizing the forming ratio, more staples can be formed and/or formed into their desired configuration. In certain examples, the surface area of thenon-forming portion 4508 of theanvil 4500 can be minimized relative to thestaple forming pockets 4506. Additionally or alternatively, the footprint of thestaple forming pockets 4506 may be extended or enlarged to maximize the portion of thestaple forming surface 4502 designed to capture and form staples.

图60中示出的凹坑4506在纵向狭槽4504的第一侧上被布置成内排 4514a、中间排4514b和外排4514c。内部凹坑4506a被定位在内排4514a 中，中间凹坑4506b被定位在中间排4514b中，并且外部凹坑4506c被定位在外排4514c中。类似于砧座3800，凹坑4506沿砧座4500的钉成形表面4502布置成人字形布置。尽管未在图60中示出，在至少一个实例中，狭槽4504的相对侧上的凹坑4506可形成纵向狭槽4504的第一侧上的凹坑4506的镜像反射。在其他实例中，钉成形表面4502中的凹坑4506的布置可相对于狭槽4504不对称，并且在某些实例中，砧座4500可不包括纵向狭槽4504。在各种实例中，凹坑4506可在狭槽4504的每个侧面上被布置成少于或多于三排。Thedimples 4506 shown in Figure 60 are arranged on the first side of thelongitudinal slot 4504 in aninner row 4514a, amiddle row 4514b, and anouter row 4514c. Theinner pockets 4506a are positioned in theinner row 4514a, themiddle pockets 4506b are positioned in themiddle row 4514b, and theouter pockets 4506c are positioned in theouter row 4514c. Similar to theanvil 3800, thepockets 4506 are arranged in a herringbone arrangement along thestaple forming surface 4502 of theanvil 4500. Although not shown in FIG. 60 , in at least one example, thedimples 4506 on opposite sides of theslot 4504 may form mirror reflections of thedimples 4506 on the first side of thelongitudinal slot 4504 . In other examples, the arrangement of thepockets 4506 in thestaple forming surface 4502 may be asymmetric relative to theslots 4504, and in some examples, theanvil 4500 may not include thelongitudinal slots 4504. In various examples, thedimples 4506 may be arranged in fewer or more than three rows on each side of theslot 4504.

图60中示出的凹坑4506是相同的。限定在钉成形表面4502中的每个凹坑4506具有相同的几何结构。在其他实例中，凹坑4506的几何结构可沿砧座4500的长度逐排和/或纵向地变化。例如，在某些实例中，凹坑4506或其部分的深度可沿砧座4500的长度变化，以适应砧座和钉仓之间的间隙距离沿端部执行器和/或组织流的长度的变化，如本文所述。Thedimples 4506 shown in Figure 60 are the same. Eachpocket 4506 defined in thestaple forming surface 4502 has the same geometry. In other examples, the geometry of thepockets 4506 may vary row by row and/or longitudinally along the length of theanvil 4500 . For example, in certain instances, the depth of thepocket 4506, or a portion thereof, may vary along the length of theanvil 4500 to accommodate the variation of the gap distance between the anvil and the staple cartridge along the length of the end effector and/or tissue flow changes, as described herein.

示例性凹坑4506b在图61-63C中示出。凹坑4506b具有第一端部或近侧端部4510和第二端部或远侧端部4512。凹坑轴线PA(图61)在凹坑4506b的近侧端部4510和远侧端部4512之间延伸。凹坑4506b包括周边4516，周边4516限定凹坑4506b的边界。类似于凹坑4306，周边4516 包括在凹坑4506b的近侧端部4510和远侧端部4512处的圆角。凹坑4506b还包括近侧杯4520，远侧杯4522，以及在近侧杯4520和远侧杯4522之间延伸的颈部部分4524。当钉被驱动成与钉成形表面4502成形接触时，近侧杯4520与近侧钉腿对准，并且远侧杯4522与远侧钉腿对准。杯4520， 4522被构造成能够将钉腿朝向凹坑轴线PA和凹坑4506的中心部分(诸如颈部4524)引导或传送，并使钉腿变形成所成形的构造。Exemplary dimples 4506b are shown in Figures 61-63C. Thedimple 4506b has a first orproximal end 4510 and a second ordistal end 4512. The dimple axis PA (FIG. 61) extends between theproximal end 4510 and thedistal end 4512 of thedimple 4506b. Thedimple 4506b includes aperimeter 4516 that defines the boundary of thedimple 4506b. Similar to pocket 4306,perimeter 4516 includes rounded corners atproximal end 4510 anddistal end 4512 ofpocket 4506b. Thepocket 4506b also includes aproximal cup 4520, adistal cup 4522, and aneck portion 4524 extending between theproximal cup 4520 and thedistal cup 4522. When the staples are driven into forming contact with thestaple forming surfaces 4502, theproximal cups 4520 are aligned with the proximal staple legs and thedistal cups 4522 are aligned with the distal staple legs. Thecups 4520, 4522 are configured to guide or transport the staple legs toward the pocket axis PA and the central portion of thepocket 4506, such as theneck 4524, and deform the staple legs into the shaped configuration.

主要参见图62，凹坑4506b的每个杯4520,4522限定入口斜坡4540 和出口斜坡4542。入口斜坡4540比出口斜坡4542更陡。当形成钉时，钉腿的尖端可沿入口斜坡4540进入相应的杯4520,4522并且沿出口斜坡 4542离开相应的杯4520,4522。在入口斜坡4540和出口斜坡4542之间的顶点4546处，钉腿的尖端朝向钉基部变形以呈现成形的构造，例如诸如B形或修改的B形。凹坑4506b还在近侧杯4520和远侧杯4522之间限定桥接件4544。桥接件4544与非成形部分4508偏置。更具体地，桥接件 4544被定位在非成形部分4508下方或相对于非成形部分4508凹入。Referring primarily to Figure 62, eachcup 4520, 4522 of thepocket 4506b defines aninlet ramp 4540 and anoutlet ramp 4542. Theentrance slope 4540 is steeper than theexit slope 4542. As the staples are formed, the tips of the staple legs can enter therespective cups 4520, 4522 along the inlet ramps 4540 and exit therespective cups 4520, 4522 along the outlet ramps 4542. At the apex 4546 between theinlet ramp 4540 and theoutlet ramp 4542, the tips of the staple legs deform toward the staple base to assume a shaped configuration such as, for example, a B-shape or a modified B-shape. Thedimple 4506b also defines abridge 4544 between theproximal cup 4520 and thedistal cup 4522.Bridge 4544 is offset fromnon-formed portion 4508. More specifically, thebridges 4544 are positioned below or recessed relative to thenon-shaped portion 4508.

主要参见图63A-63C，凹坑4506b包括波状或弧形壁4550。壁4550 将每个杯4520,5422形成为宽的圆形盆，用于接收和形成钉腿。另外，凹坑4506b包括沿底表面的凹槽4556。壁4550向下作弧形运动而进入非成形表面4508和凹槽4556之间的砧座4500中。例如，侧壁4550无缝地过渡到凹坑4506b的底表面。凹槽4556沿底表面从近侧杯4520延伸越过桥接件4524并进入远侧杯4522。凹槽4556被构造成能够在钉腿运动到变形构型时约束和引导钉腿。在各种实例中，凹槽4556的直径可小于与凹槽4556接合的钉的直径。在端部执行器中，其中不同的钉几何结构与相同的钉成形凹坑几何结构一起使用，凹坑中的凹槽的宽度可小于最小直径的钉。Referring primarily to FIGS. 63A-63C , thedimple 4506b includes a wavy orarcuate wall 4550 .Wall 4550 forms eachcup 4520, 5422 into a wide circular basin for receiving and forming staple legs. Additionally, thedimples 4506b includegrooves 4556 along the bottom surface.Wall 4550 arcs downward intoanvil 4500 betweennon-forming surface 4508 andgroove 4556. For example,sidewall 4550 seamlessly transitions to the bottom surface ofdimple 4506b. Thegroove 4556 extends along the bottom surface from theproximal cup 4520 past thebridge 4524 and into thedistal cup 4522. Thegrooves 4556 are configured to constrain and guide the staple legs as they move to the deformed configuration. In various examples, the diameter of thegrooves 4556 can be smaller than the diameter of the staples with which thegrooves 4556 engage. In end effectors where different staple geometries are used with the same staple forming pocket geometry, the width of the grooves in the pockets may be smaller than the smallest diameter staple.

波状壁4550在每个杯4520,4522的外端和颈部部分4524之间变窄。更具体地，壁4550沿向内轮廓延伸，以在凹坑4506b的周边4516中限定轮廓。加宽的区域提供用于接收钉腿的尖端的扩大的占有面积。当杯4520, 4522朝向桥接件4544变窄时，杯4520,4522被构造成能够朝向和/或沿凹坑轴线PA传送和/或引导钉腿的尖端并且进入成形构造。Thecorrugated wall 4550 narrows between the outer end of eachcup 4520, 4522 and theneck portion 4524. More specifically, thewall 4550 extends along an inward contour to define a contour in theperimeter 4516 of thepocket 4506b. The widened area provides an enlarged footprint for receiving the tips of the staple legs. As thecups 4520, 4522 narrow toward thebridge 4544, thecups 4520, 4522 are configured to transmit and/or guide the tips of the staple legs toward and/or along the pocket axis PA and into the shaped configuration.

凹坑4506b还沿凹坑4506b的侧面的一部分限定倒角边缘4554。当侧壁4550朝向颈部部分4524变窄时，倒角边缘4554的宽度相应地朝向颈部部分4224扩展，以保持总凹坑宽度。Thedimple 4506b also defines a chamferededge 4554 along a portion of the side of thedimple 4506b. As thesidewall 4550 narrows toward theneck portion 4524, the width of the chamferededge 4554 correspondingly expands toward theneck portion 4224 to maintain the overall dimple width.

再次参见图61，凹坑4506b关于凹坑轴线PA对称。例如，凹坑4406b 的周边4516关于凹坑轴线PA对称。此外，凹坑4506b关于穿过颈部部分4524并垂直于凹坑轴线PA的中心轴线CA对称。例如，凹坑4506b 的周边4516关于中心轴线CA对称，并且近侧杯4520具有与远侧杯4522 相同的几何结构。在其他实例中，近侧杯4520可与远侧杯4522不同。例如，再次参见图62，远侧深度D₂可小于近侧深度D₁，以适应砧座和钉仓和/或组织流之间的间隙距离的变化，如本文所述。Referring again to Figure 61, thedimple 4506b is symmetrical about the dimple axis PA. For example, theperimeter 4516 of thedimple 4406b is symmetrical about the dimple axis PA. Furthermore, thedimple 4506b is symmetrical about a central axis CA that passes through theneck portion 4524 and is perpendicular to the dimple axis PA. For example, theperimeter 4516 of thepocket 4506b is symmetrical about the central axis CA, and theproximal cup 4520 has the same geometry as thedistal cup 4522. In other examples, theproximal cup 4520 can be different from thedistal cup 4522. For example, referring again to Figure 62, the distal depth D2 may be less_than the proximal depth_D1 to accommodate variations in the gap distance between the anvil and the staple cartridge and/or tissue flow, as described herein.

再次参见图60，每个凹坑4506朝向相邻凹坑4506的颈部部分4524 延伸。例如，中间凹坑4506b与内部凹坑4506a和外部凹坑4506c的颈部部分4524对准。此外，内部凹坑4506a和外部凹坑4506b朝向中间凹坑 4506b中的一个的颈部部分4524延伸。Referring again to FIG. 60 , eachdimple 4506 extends toward theneck portion 4524 of anadjacent dimple 4506 . For example, themiddle pocket 4506b is aligned with theneck portions 4524 of theinner pocket 4506a andouter pocket 4506c. Additionally, theinner dimple 4506a and theouter dimple 4506b extend toward theneck portion 4524 of one of theintermediate dimples 4506b.

钉成形凹坑可包括延伸着陆区，用于在钉被击发成与砧座成形接触时接收钉腿的尖端。在某些实例中，如本文所述，延伸着陆区可从钉成形凹坑的杯侧向和/或纵向延伸。钉成形凹坑的轮廓或周边可与一个或多个相邻的钉成形凹坑的轮廓或周边嵌套。例如，钉成形凹坑的周边的至少一部分可沿轮廓或路径延伸，该轮廓或路径匹配、跟踪、跟随和/或平行于一个或多个相邻的钉成形凹坑的周边的一部分。这种跟踪部分或相邻周边可限定同心轮廓。The staple forming pockets may include extended landing areas for receiving the tips of the staple legs when the staples are fired into forming contact with the anvil. In certain instances, as described herein, the extended landing zone may extend laterally and/or longitudinally from the cups of the staple forming pockets. The profile or perimeter of a staple forming pocket may nest with the profile or perimeter of one or more adjacent staple forming pockets. For example, at least a portion of the perimeter of a staple-forming pocket may extend along a contour or path that matches, tracks, follows, and/or is parallel to a portion of the perimeter of one or more adjacent staple-forming pockets. Such tracking portions or adjacent perimeters may define concentric contours.

在各种实例中，具有一个或多个延伸着陆区的钉成形凹坑的表面区域可大于没有一个或多个延伸着陆区的钉成形凹坑的表面区域。例如，延伸着陆区可使钉成形凹坑的表面区域增加至少10％。例如，延伸着陆区可使钉成形凹坑的表面区域增加15％或25％。在其他实例中，延伸着陆区可使钉成形凹坑的表面区域增加小于10％，例如诸如5％。本文所述的某些钉成形凹坑可具有比具有六排平行的钉成形凹坑的砧座中的钉成形凹坑更大的表面区域，但是其以其他方式与本文所述的具有六排成角度取向的钉成形凹坑的某些砧座相同。在其他实例中，具有延伸着陆区的钉成形凹坑还可包括变窄和/或以其他方式减小的部分，其表面区域等于或大于延伸着陆区的表面区域。In various examples, the surface area of the staple-forming pockets with one or more extended landing zones may be greater than the surface area of the staple-forming pockets without the one or more extended landing zones. For example, extending the landing zone can increase the surface area of the staple forming pockets by at least 10%. For example, extending the landing zone can increase the surface area of the staple forming pockets by 15% or 25%. In other examples, extending the landing zone can increase the surface area of the staple forming pockets by less than 10%, such as, for example, 5%. Certain staple-forming pockets described herein may have a larger surface area than staple-forming pockets in an anvil having six parallel rows of staple-forming pockets, but are otherwise different from those described herein with six rows of staple-forming pockets Certain anvils of the angled staple forming pockets are identical. In other examples, a staple forming pocket with an extended landing zone may also include a narrowed and/or otherwise reduced portion having a surface area equal to or greater than that of the extended landing zone.

在某些实例中，钉成形凹坑可以是不对称的。例如，钉成形凹坑相对于在凹坑的近侧端部和远侧端部之间延伸的凹坑轴线可以是不对称的和/或可相对于垂直于凹坑轴线延伸并且横切凹坑的中心部分的中心轴线不对称。例如，钉成形凹坑的不对称性可促进凹坑的嵌套和/或可最大化钉成形表面中的凹坑的表面区域。In some instances, the staple forming pockets may be asymmetrical. For example, the staple forming pockets may be asymmetrical relative to a pocket axis extending between the proximal and distal ends of the pockets and/or may extend perpendicular to the pocket axis and traverse the pockets The central axis of the central part is asymmetrical. For example, the asymmetry of the staple forming pockets may facilitate nesting of the pockets and/or may maximize the surface area of the pockets in the staple forming surface.

现在参见图64-67C，示出了砧座5000的一部分中的钉成形凹坑5006。类似于砧座3800，凹坑5006沿砧座5000的钉成形表面5002布置成人字形布置。砧座5000包括钉成形表面5002和纵向狭槽5004。纵向狭槽5004 沿砧座5000的纵向轴线LA延伸。在某些实例中，击发元件和/或切割元件可在击发行程的至少一部分期间平移穿过纵向狭槽5004。钉成形凹坑 5006限定在钉成形表面5002中。钉成形表面5002还包括围绕凹坑5006 延伸的非成形部分5008。非成形部分5008完全围绕每个凹坑5006延伸。换句话说，非成形部分5008围绕钉成形凹坑5006。在其他实例中，两个或更多个相邻凹坑5006的至少一部分可邻接接触，使得非成形部分5008 不被定位在两者间。Referring now to Figures 64-67C,staple forming pockets 5006 in a portion ofanvil 5000 are shown. Similar to theanvil 3800, thepockets 5006 are arranged in a herringbone arrangement along thestaple forming surface 5002 of theanvil 5000.Anvil 5000 includesstaple forming surface 5002 andlongitudinal slot 5004. Thelongitudinal slot 5004 extends along the longitudinal axis LA of theanvil 5000 . In certain examples, the firing element and/or cutting element can translate throughlongitudinal slot 5004 during at least a portion of the firing stroke.Staple forming pockets 5006 are defined in thestaple forming surface 5002. Thestaple forming surface 5002 also includes anon-forming portion 5008 extending around thepocket 5006 . Anon-shaped portion 5008 extends completely around eachpocket 5006. In other words, thenon-formed portion 5008 forms thepocket 5006 around the staple. In other examples, at least a portion of two or moreadjacent pockets 5006 may be in abutting contact such that thenon-shaped portion 5008 is not positioned therebetween.

可优化钉成形表面5002的成形比。通过优化成形比，更多的钉可成形和/或成形为他们期望的构造。在某些实例中，砧座5000的非成形部分5008的表面区域可相对于钉成形凹坑5006被最小化。除此之外或另选地，钉成形凹坑5006的占有面积可延伸或扩大，以最大化钉成形表面 5002的被设计用于捕获和形成钉的部分。The forming ratio of thestaple forming surface 5002 can be optimized. By optimizing the forming ratio, more staples can be formed and/or formed into their desired configuration. In certain examples, the surface area of thenon-forming portion 5008 of theanvil 5000 can be minimized relative to thestaple forming pockets 5006. Additionally or alternatively, the footprint of thestaple forming pockets 5006 may be extended or enlarged to maximize the portion of thestaple forming surface 5002 designed to capture and form staples.

图64中示出的凹坑5006在纵向狭槽5004的第一侧上被布置成内排 5014a、中间排5014b和外排5014c。内部凹坑5006a被定位在内排5014a 中，中间凹坑5006b被定位在中间排5014b中，并且外部凹坑5006c被定位在外排5014c中。尽管未在图64中示出，在至少一个实例中，狭槽5004 的相对侧上的凹坑5006可形成纵向狭槽5004的第一侧上的凹坑5006的镜像反射。在其他实例中，钉成形表面5002中的凹坑5006的布置可相对于狭槽5004不对称，并且在某些实例中，砧座5000可不包括纵向狭槽5004。在各种实例中，凹坑5006可在狭槽5004的每个侧面上被布置成少于或多于三排。Thedimples 5006 shown in Figure 64 are arranged on the first side of thelongitudinal slot 5004 in an inner row 5014a, a middle row 5014b, and anouter row 5014c. The inner pocket 5006a is positioned in the inner row 5014a, themiddle pocket 5006b is positioned in the middle row 5014b, and theouter pocket 5006c is positioned in theouter row 5014c. Although not shown in FIG. 64 , in at least one example, thedimples 5006 on opposite sides of theslot 5004 may form mirror reflections of thedimples 5006 on the first side of thelongitudinal slot 5004 . In other examples, the arrangement of thepockets 5006 in thestaple forming surface 5002 may be asymmetrical relative to theslots 5004, and in some examples, theanvil 5000 may not include thelongitudinal slots 5004. In various examples, thedimples 5006 may be arranged in fewer or more than three rows on each side of theslot 5004 .

内部凹坑5006a相同，中间凹坑5006b相同，并且外部凹坑5006c相同；然而，内部凹坑5006a与中间凹坑5006b和外部凹坑5006c不同，并且中间凹坑5006b与外部凹坑5006c不同。换句话说，每个排5014a，5014b 和5014c中的凹坑5006是不同的。本文描述的凹坑5006a，5006b和5006c 的延伸着陆区5030和5032有助于其不同的几何结构。延伸着陆区5030 和5032的形状和尺寸由相邻的嵌套凹坑5006的周边5016限制。The inner pocket 5006a is the same, themiddle pocket 5006b is the same, and theouter pocket 5006c is the same; however, the inner pocket 5006a is different from themiddle pocket 5006b and theouter pocket 5006c, and themiddle pocket 5006b is different from theouter pocket 5006c. In other words, thedimples 5006 in eachrow 5014a, 5014b and 5014c are different. Theextended landing areas 5030 and 5032 of thedimples 5006a, 5006b and 5006c described herein contribute to their different geometries. The shape and size of theextended landing zones 5030 and 5032 are limited by theperimeter 5016 of the adjacent nested pockets 5006 .

尽管每个排5014a，5014b和5014c中的凹坑5006是不同的，但是凹坑5006可被构造成能够将钉形成为相同或基本上相同的成形形状。在其他实例中，凹坑5006可被构造成能够使钉成形为不同形状的钉，诸如不同的高度和/或构造。在某些实例中，凹坑5006可在每个排5014a，5014b 和5014c内纵向变化。例如，在某些实例中，凹坑5006或其部分的深度可沿砧座5000的长度变化，以适应砧座和钉仓之间的间隙距离沿端部执行器和/或组织流的长度的变化，如本文所述。Although thedimples 5006 in eachrow 5014a, 5014b, and 5014c are different, thedimples 5006 may be configured to form staples into the same or substantially the same shaped shape. In other examples, thepockets 5006 may be configured to enable the staples to be formed into differently shaped staples, such as different heights and/or configurations. In some examples, thedimples 5006 may vary longitudinally within eachrow 5014a, 5014b, and 5014c. For example, in certain instances, the depth of thepocket 5006, or a portion thereof, may vary along the length of theanvil 5000 to accommodate the variation of the gap distance between the anvil and the staple cartridge along the length of the end effector and/or tissue flow changes, as described herein.

在某些实例中，凹坑5006可被构造成能够接合不同几何结构的钉。例如，具有不同的未成形高度和/或不同直径的钉可通过砧座5000中的凹坑5006形成。在某些实例中，钉的几何结构可纵向变化，并且凹坑5006 可被构造成能够形成不同的几何结构的钉。例如，钉的未成形高度和/ 或线直径可沿砧座5000的长度变化。In some instances, thepockets 5006 can be configured to engage pins of different geometries. For example, staples having different unformed heights and/or different diameters may be formed through thepockets 5006 in theanvil 5000 . In some examples, the geometry of the staples can vary longitudinally, and thepockets 5006 can be configured to form staples of different geometries. For example, the unformed height and/or wire diameter of the staples may vary along the length of theanvil 5000.

示例性中间凹坑5006b在图64-67C中示出。凹坑5006b具有第一端部或近侧端部5010和第二端部或远侧端部5012。凹坑轴线PA(图65) 在凹坑5006b的近侧端部5010和远侧端部5012之间延伸。凹坑5006b包括周边5016，周边5016限定凹坑5006b的边界。周边5016包括线性部分和波状部分。更具体地，周边5016包括线性部分和在其间的波状拐角，线性部分在该拐角处改变方向。再次参见图64，每个凹坑5006的周边 5016的至少一部分紧密地跟踪或平行于一个或多个相邻凹坑5006的周边的至少一部分。An exemplaryintermediate dimple 5006b is shown in Figures 64-67C. Thedimple 5006b has a first orproximal end 5010 and a second ordistal end 5012. The dimple axis PA (FIG. 65) extends between theproximal end 5010 and thedistal end 5012 of thedimple 5006b. Thedimple 5006b includes aperimeter 5016 that defines the boundary of thedimple 5006b. Theperimeter 5016 includes a linear portion and a wavy portion. More specifically, theperimeter 5016 includes linear portions and undulating corners therebetween where the linear portions change direction. Referring again to Figure 64, at least a portion of theperimeter 5016 of eachpocket 5006 closely tracks or is parallel to at least a portion of the perimeter of one or moreadjacent pockets 5006.

凹坑5006b还包括近侧杯5020，远侧杯5022，以及在近侧杯5020和远侧杯5022之间延伸的颈部部分5024。当钉被驱动成与钉成形表面5002 成形接触时，近侧杯5020与近侧钉腿对准，并且远侧杯5022与远侧钉腿对准。杯5020和5022被构造成能够将钉腿朝向凹坑轴线PA和凹坑 5006的中心部分(诸如颈部部分5024)引导或传送，并使钉腿变形成所成形的构造。Thepocket 5006b also includes aproximal cup 5020, adistal cup 5022, and aneck portion 5024 extending between theproximal cup 5020 and thedistal cup 5022. When the staples are driven into forming contact with thestaple forming surfaces 5002, theproximal cups 5020 are aligned with the proximal staple legs and thedistal cups 5022 are aligned with the distal staple legs.Cups 5020 and 5022 are configured to guide or transport the staple legs toward pocket axis PA and a central portion ofpocket 5006, such asneck portion 5024, and deform the staple legs into the shaped configuration.

主要参见图66，凹坑5006b的每个杯5020,5022限定入口斜坡5040 和出口斜坡5042。当形成钉时，钉腿的尖端可沿入口斜坡5040进入相应的凹坑5020,5022并且沿出口斜坡5042离开相应的凹坑5020,5022。在入口斜坡5040和出口斜坡5042之间的顶点5046处，钉腿的尖端朝向钉基部变形以呈现成形的构造，例如诸如B形或修改的B形。凹坑5006b还在近侧杯5020和远侧杯5022之间的颈部部分5024中限定桥接件5044。桥接件5044与非成形部分5008偏置。更具体地，桥接件5044被定位在非成形部分5008下方或相对于非成形部分5008凹入。Referring primarily to Figure 66, eachcup 5020, 5022 of thepocket 5006b defines aninlet ramp 5040 and anoutlet ramp 5042. As the staples are formed, the tips of the staple legs can enter the correspondingpockets 5020 , 5022 along theentry ramp 5040 and exit therespective pockets 5020 , 5022 along theexit ramp 5042 . At the apex 5046 between theinlet ramp 5040 and theoutlet ramp 5042, the tips of the staple legs deform toward the staple base to assume a shaped configuration, such as, for example, a B-shape or a modified B-shape. Thepocket 5006b also defines abridge 5044 in theneck portion 5024 between theproximal cup 5020 and thedistal cup 5022.Bridge 5044 is offset fromnon-formed portion 5008 . More specifically, thebridges 5044 are positioned below or recessed relative to thenon-shaped portion 5008 .

主要参见图67A-67C，凹坑5006b包括侧壁5050，侧壁5050从非成形部分5008延伸到底表面5058。侧壁5050包括线性部分和波状部分。侧壁5050朝向每个杯5020,5022的中心区域5021(图65)变宽，并且从每个杯5020,5022的中心区域5021朝向颈部部分5024变窄。加宽的中心区域5021提供了用于接收钉腿的尖端的扩大的占有面积。当杯5020,5022 朝向颈部部分5024变窄时，杯5020,5022被构造成能够朝向和/或沿凹坑轴线PA传送和/或引导其钉腿和尖端并且进入成形构造。Referring primarily to FIGS. 67A-67C , thedimple 5006b includes sidewalls 5050 that extend from thenon-formed portion 5008 to thebottom surface 5058 .Sidewall 5050 includes linear portions and undulating portions. Theside wall 5050 widens toward the central region 5021 ( FIG. 65 ) of eachcup 5020 , 5022 and narrows from thecentral region 5021 of eachcup 5020 , 5022 toward theneck portion 5024 . The widenedcentral region 5021 provides an enlarged footprint for receiving the tips of the staple legs. As thecups 5020, 5022 narrow toward theneck portion 5024, thecups 5020, 5022 are configured to transmit and/or guide their legs and tips toward and/or along the pocket axis PA and into the shaped configuration.

图67A沿图65中的平面ALL截取，其对应于钉腿的预期着陆位置 (ALL)。例如，可预期钉腿的尖端在平面ALL和凹坑轴线PA的交叉处和/或附近着陆在近侧杯5020中。在平面ALL处，凹坑5006b限定宽度W_A和深度D_A。图67B中的横截面横跨近侧杯5020和颈部5024之间的过渡截取。图67B示出了限定宽度W_B和深度D_B的凹坑5006b。宽度 W_B小于宽度W_A，并且深度D_B大于深度D_A。换句话说，凹坑5006b从近侧杯5020中的平面ALL朝向颈部5024变窄并加深。平面ALL处的相对大的宽度W_A被构造成能够提供用于接收钉腿的宽容器或盆。图67C 中的横截面横跨颈部部分5024截取。图67C示出了限定宽度W_C和深度 D_C的凹坑5006b。宽度W_C小于宽度W_B，并且深度D_C小于深度D_B。换句话说，凹坑5006b继续变窄，并且在横跨桥接件5044的颈部5024中变得更浅。Figure 67A is taken along plane ALL in Figure 65, which corresponds to the intended landing position (ALL) of the staple legs. For example, the tips of the staple legs may be expected to land in theproximal cup 5020 at and/or near the intersection of the plane ALL and the dimple axis PA. At plane ALL, pit_5006b defines width WA and depth DA_. The cross-section in FIG. 67B is taken across the transition between theproximal cup 5020 and theneck 5024. FIG._67B shows a dimple_5006b defining a width WB and a depth DB. Width_WB is less than width_WA and depth_DB is greater than depth DA_. In other words, thedimple 5006b narrows and deepens from the plane ALL in theproximal cup 5020 toward theneck 5024. The relatively large width WA at plane ALL is configured to provide_a wide receptacle or pot for receiving the spike legs. The cross-section in FIG. 67C is taken across theneck portion 5024. FIG._67C shows a pit_5006b defining a width WC and a depth DC. Width_WC is less than width_WB , and depth_DC is less than depth_DB . In other words, thedimple 5006b continues to narrow and become shallower in theneck 5024 across thebridge 5044.

凹坑5006b的底表面5058是平坦表面，其由其周围的弧形圆角5059 界定。在某些实例中，底表面5058可具有沿其至少一部分限定的凹槽。在其他实例中，底表面5058可形成槽。在其他实例中，底表面可包括沿其至少一部分(例如诸如横跨桥接件5044)的隆起或脊。Thebottom surface 5058 of thedimple 5006b is a flat surface that is bounded byarcuate fillets 5059 around it. In certain examples, thebottom surface 5058 can have grooves defined along at least a portion thereof. In other examples, thebottom surface 5058 can form grooves. In other examples, the bottom surface may include ridges or ridges along at least a portion thereof (eg, such as across bridges 5044).

现在主要参见图65，凹坑5006b包括近侧延伸着陆区5030和远侧延伸着陆区5032。近侧延伸着陆区5030被定位在近侧杯5020的近侧部分中，并且远侧延伸着陆区5032被定位在远侧杯5022的远侧部分中。更具体地，延伸着陆区5030和5032被定位在钉的预期着陆位置之外。例如，近侧延伸着陆区5030被定位在平面ALL的近侧，并且在钉腿的尖端着陆在平面ALL之外的实例中，近侧延伸着陆区5030可捕获钉腿并将其引导朝向凹坑轴线PA和/或朝向颈部部分5024。着陆区5030和5032 限定大致多边形形状，并且更具体地，限定具有圆角的四边形。在其他实例中，着陆区5030和5032可以是三角形或基本上三角形，并且在其他实例中，例如可限定弧形或球形轮廓。Referring now primarily to FIG. 65 , thedimple 5006b includes a proximally extendinglanding zone 5030 and a distally extendinglanding zone 5032 . A proximally extendinglanding zone 5030 is positioned in the proximal portion of theproximal cup 5020 and a distally extendinglanding zone 5032 is positioned in the distal portion of thedistal cup 5022. More specifically, theextended landing zones 5030 and 5032 are positioned outside the intended landing position of the staples. For example, the proximally extendinglanding zone 5030 is positioned proximal of the plane ALL, and in instances where the tips of the staple legs land outside of the plane ALL, the proximally extendinglanding zone 5030 can capture the staple legs and guide them towards the pockets Axis PA and/or towards theneck portion 5024.Landing zones 5030 and 5032 define a generally polygonal shape, and more specifically, a quadrilateral with rounded corners. In other examples, thelanding zones 5030 and 5032 may be triangular or substantially triangular, and in other examples, may define arcuate or spherical profiles, for example.

延伸着陆区5030和5032的几何结构由相邻钉成形凹坑5006的周边 5016限制。例如，延伸着陆区5030和5032可朝向一个或多个相邻的钉成形凹坑延伸和/或几乎与其邻接接触。延伸着陆区5030和5032和/或凹坑5006b的其他部分可平行于相邻的钉成形凹坑5006跟踪和/或延伸。在其他实例中，延伸着陆区5030和5032可邻接一个或多个相邻的钉成形凹坑5006。The geometry of theextended landing zones 5030 and 5032 is limited by theperimeter 5016 of the adjacentstaple forming pockets 5006. For example,extension landing zones 5030 and 5032 may extend toward and/or be in nearly contiguous contact with one or more adjacent staple forming pockets. Theextension landings 5030 and 5032 and/or other portions of thepockets 5006b may track and/or extend parallel to adjacentstaple forming pockets 5006 . In other examples,extended landing areas 5030 and 5032 may abut one or more adjacentstaple forming pockets 5006 .

再次参见图65，凹坑5006b关于凹坑轴线PA不对称。例如，凹坑 5006b的周边5016关于凹坑轴线PA不对称。此外，凹坑5006b关于穿过颈部部分5024并垂直于凹坑轴线PA的中心轴线CA不对称。例如，凹坑5006b的周边5016关于中心轴线CA不对称，并且近侧杯5020具有与远侧杯5022不同的几何结构。尽管近侧杯5020和远侧杯5022是不同的，但是凹坑5006b可被构造成能够形成对称的钉。例如，再次参见图66，远侧深度D₂可小于近侧深度D₁，以适应砧座和钉仓和/或组织流之间的间隙距离的变化，如本文所述。钉的近侧腿部和远侧腿部的成形高度可相等。在其他实例中，凹坑5006可被构造成能够形成不对称的钉。Referring again to Figure 65, thedimple 5006b is asymmetric about the dimple axis PA. For example, theperimeter 5016 of thedimple 5006b is asymmetric about the dimple axis PA. Additionally, thedimple 5006b is asymmetrical about a central axis CA that passes through theneck portion 5024 and is perpendicular to the dimple axis PA. For example, theperimeter 5016 of thepocket 5006b is asymmetric about the central axis CA, and theproximal cup 5020 has a different geometry than thedistal cup 5022. Although theproximal cup 5020 and thedistal cup 5022 are different, thepockets 5006b can be configured to form symmetrical staples. For example, referring again to Figure 66, the distal depth D2 may be less_than the proximal depth_D1 to accommodate variations in the gap distance between the anvil and the staple cartridge and/or tissue flow, as described herein. The formed height of the proximal and distal legs of the staple may be equal. In other examples, thedimples 5006 may be configured to form asymmetrical staples.

再次参见图65，颈部部分5024比近侧杯5020和远侧杯5022窄。颈部部分5024处的凹坑5006b的变窄的周边5016在近侧杯5020的一部分和远侧杯5022的一部分之间限定接收半岛部5026。接收半岛部5026被定位在凹坑5006b的每个侧面上。接收半岛部5026由凹坑5006b的周边 5016和切线轴线(例如，T_B1和T_B2)界定，该切线轴线与凹坑5006的每个侧面上的近侧杯5020和远侧杯5022的最宽部分相切。第一切线轴线 T_B1被定位在凹坑5006b的第一侧上，并且第二切线轴线T_B2被定位在凹坑5006b的相对侧上。图69 中示出的第一切线轴线T_B1和第二切线轴线 T_B2与凹坑轴线PA平行。在其他实例中，切线轴线T_B1和T_B2中的一个或两个可不与凹坑轴线PA平行。Referring again to FIG. 65, theneck portion 5024 is narrower than theproximal cup 5020 and thedistal cup 5022. The narrowedperimeter 5016 of thepocket 5006b at theneck portion 5024 defines a receivingpeninsula 5026 between a portion of theproximal cup 5020 and a portion of thedistal cup 5022. Receivingpeninsulas 5026 are positioned on each side of thepocket 5006b. The receivingpeninsula 5026 is bounded by theperimeter 5016 of thepocket 5006b and the tangential axis (eg, T_B1 and T_B2 ) that is the widest of the proximal anddistal cups 5020 and 5022 on each side of thepocket 5006 Partially tangent. The first tangential axis TB1 is positioned on a first side of the pocket_5006b and the second tangential axis_TB2 is positioned on the opposite side of thepocket 5006b. The first tangential axis_TB1 and the second tangential axis_TB2 shown in FIG. 69 are parallel to the pit axis PA. In other examples, one or both of the tangential axes T_B1 and T_B2 may not be parallel to the dimple axis PA.

再次参见图64，凹坑5006的周边5016沿钉成形表面5002嵌套或互锁。具体地，每个凹坑5006延伸到相邻凹坑5006的接收半岛部5026中。例如，中间凹坑5006b嵌套在内部凹坑5006a和外部凹坑5006c之间。换句话说，中间凹坑5006b延伸到相邻内部凹坑5006a的接收半岛部5026 中并且延伸到相邻外部凹坑5006c的接收半岛部5026中。此外，内部凹坑5006a和外部凹坑5006b与中间凹坑5006b嵌套。更具体地，内部凹坑 5006a延伸到相邻中间凹坑5006b的接收半岛部5026中，并且外部凹坑 5006c延伸到相邻中间凹坑5006b的接收半岛部5026中。在各种实例中，中间凹坑5006b的远侧延伸着陆区5032被定位在内部凹坑5006a的接收半岛部5026中，中间凹坑5006b的近侧延伸着陆区5030被定位在外部凹坑5006c的接收半岛部5026中，内部凹坑5006a的远侧延伸着陆区5032 被定位在中间凹坑5006b的接收半岛部5026中，并且外部凹坑5006c的近侧延伸着陆区5030被定位在中间凹坑5006b的接收半岛部5026中。Referring again to FIG. 64, theperimeters 5016 of thepockets 5006 nest or interlock along thestaple forming surface 5002. Specifically, eachpocket 5006 extends into the receivingpeninsula 5026 of anadjacent pocket 5006 . For example,middle pocket 5006b is nested between inner pocket 5006a andouter pocket 5006c. In other words, themiddle pocket 5006b extends into the receivingpeninsula 5026 of the adjacent inner pocket 5006a and into the receivingpeninsula 5026 of the adjacentouter pocket 5006c. In addition, inner dimple 5006a andouter dimple 5006b are nested withmiddle dimple 5006b. More specifically, the inner pocket 5006a extends into the receivingpeninsula 5026 of the adjacentintermediate pocket 5006b, and theouter pocket 5006c extends into the receivingpeninsula 5026 of the adjacentintermediate pocket 5006b. In various examples, the distally extendinglanding zone 5032 of themiddle pocket 5006b is positioned in the receivingpeninsula 5026 of the inner pocket 5006a and the proximally extendinglanding zone 5030 of themiddle pocket 5006b is positioned in theouter pocket 5006c In the receivingpeninsula 5026, thedistally extending land 5032 of the inner pocket 5006a is positioned in the receivingpeninsula 5026 of themiddle pocket 5006b, and theproximally extending land 5030 of theouter pocket 5006c is positioned within themiddle pocket 5006b The receivingpeninsula section 5026.

凹坑5006的几何结构便于凹坑5006在钉成形表面5002中的嵌套。例如，因为凹坑5006包括在两个扩大的杯5020和5022之间的变窄的颈部部分5024，所以另一个凹坑5006的扩大的杯5020,5022中的一个可定位成邻近变窄的颈部部分5024。例如，扩大的杯5020,5022中的一个可与相邻的凹坑5006的一部分对准和/或被其接收。在所述实例中，可优化由凹坑5006覆盖的钉成形表面5002的表面区域。钉成形表面5002的“成形比”是非成形部分5008与成形部分(即，凹坑5006)的比率。钉成形表面5002的成形比为约1:1。在其他实例中，成形比可小于1:1或大于1:1。例如，在至少一个实例中，钉成形表面5002的50％以上可用钉成形凹坑5006覆盖。在另一个实例中，钉成形表面5002的60％以上或 75％以上可用钉成形凹坑5006覆盖。The geometry of thedimples 5006 facilitates the nesting of thedimples 5006 in thestaple forming surface 5002. For example, becausedimple 5006 includes a narrowedneck portion 5024 between twoenlarged cups 5020 and 5022, one of theenlarged cups 5020, 5022 of anotherdimple 5006 may be positioned adjacent to the narrowedNeck section 5024. For example, one of theenlarged cups 5020 , 5022 may be aligned with and/or received by a portion of theadjacent pocket 5006 . In the example, the surface area of thestaple forming surface 5002 covered by thedimples 5006 can be optimized. The "form ratio" of thestaple forming surface 5002 is the ratio of thenon-formed portion 5008 to the formed portion (ie, the dimples 5006). The forming ratio of thestaple forming surface 5002 is about 1:1. In other examples, the forming ratio may be less than 1:1 or greater than 1:1. For example, in at least one example, more than 50% of thestaple forming surface 5002 can be covered with thestaple forming pockets 5006. In another example, more than 60% or more than 75% of thestaple forming surface 5002 may be covered with thestaple forming pockets 5006.

现在参见图68-71C，示出了砧座5100的一部分中的钉成形凹坑5106。类似于砧座3800，凹坑5106沿砧座5100的钉成形表面5102布置成人字形布置。砧座5100包括钉成形表面5102和纵向狭槽5104。纵向狭槽5104 沿砧座5100的纵向轴线LA延伸。在某些实例中，击发元件和/或切割元件可在击发行程的至少一部分期间平移穿过纵向狭槽5104。钉成形凹坑5106限定在钉成形表面5102中。钉成形表面5102还包括围绕凹坑5106 延伸的非成形部分5108。非成形部分5108完全围绕每个凹坑5106延伸。换句话说，非成形部分5108围绕钉成形凹坑5106。在其他实例中，两个或更多个相邻凹坑5106的至少一部分可邻接接触，使得非成形部分5108 不被定位在两者间。Referring now to Figures 68-71C,staple forming pockets 5106 in a portion ofanvil 5100 are shown. Similar to theanvil 3800, thepockets 5106 are arranged in a herringbone arrangement along thestaple forming surface 5102 of theanvil 5100.Anvil 5100 includesstaple forming surface 5102 andlongitudinal slot 5104. Thelongitudinal slot 5104 extends along the longitudinal axis LA of theanvil 5100. In certain examples, the firing element and/or cutting element can translate throughlongitudinal slot 5104 during at least a portion of the firing stroke.Staple forming pockets 5106 are defined in thestaple forming surface 5102. Thestaple forming surface 5102 also includes anon-forming portion 5108 extending around thedimples 5106 . Thenon-formed portion 5108 extends completely around eachpocket 5106. In other words, thenon-formed portion 5108 forms thepocket 5106 around the staple. In other examples, at least a portion of two or moreadjacent pockets 5106 may be in abutting contact such that thenon-shaped portion 5108 is not positioned therebetween.

可优化钉成形表面5102的成形比。通过优化成形比，更多的钉可成形和/或成形为他们期望的构造。在某些实例中，砧座5100的非成形部分5108的表面区域可相对于钉成形凹坑5106被最小化。除此之外或另选地，钉成形凹坑5106的占有面积可延伸或扩大，以最大化钉成形表面 5102的被设计用于捕获和形成钉的部分。The forming ratio of thestaple forming surface 5102 can be optimized. By optimizing the forming ratio, more staples can be formed and/or formed into their desired configuration. In certain examples, the surface area of thenon-forming portion 5108 of theanvil 5100 can be minimized relative to thestaple forming pockets 5106. Additionally or alternatively, the footprint of thestaple forming pockets 5106 may be extended or enlarged to maximize the portion of thestaple forming surface 5102 designed to capture and form staples.

图68中示出的凹坑5106在纵向狭槽5104的第一侧上被布置成内排 5114a、中间排5114b和外排5114c。内部凹坑5106a被定位在内排5114a 中，中间凹坑5106b被定位在中间排5114b中，并且外部凹坑5106c被定位在外排5114c中。尽管未在图68中示出，在至少一个实例中，狭槽5104 的相对侧上的凹坑5106可形成纵向狭槽5104的第一侧上的凹坑5106的镜像反射。在其他实例中，钉成形表面5102中的凹坑5106的布置可相对于狭槽5104不对称，并且在某些实例中，砧座5100可不包括纵向狭槽5104。在各种实例中，凹坑5106可在狭槽5104的每个侧面上被布置成少于或多于三排。Thedimples 5106 shown in Figure 68 are arranged on the first side of thelongitudinal slot 5104 in aninner row 5114a, amiddle row 5114b and anouter row 5114c. Theinner pockets 5106a are positioned in theinner row 5114a, themiddle pockets 5106b are positioned in themiddle row 5114b, and theouter pockets 5106c are positioned in theouter row 5114c. Although not shown in FIG. 68 , in at least one example, thedimples 5106 on opposite sides of theslot 5104 may form mirror reflections of thedimples 5106 on the first side of thelongitudinal slot 5104 . In other examples, the arrangement of thepockets 5106 in thestaple forming surface 5102 may be asymmetric relative to theslots 5104, and in some examples, theanvil 5100 may not include thelongitudinal slots 5104. In various examples, thedimples 5106 may be arranged in fewer or more than three rows on each side of theslot 5104.

内部凹坑5106a相同，中间凹坑5106b相同，并且外部凹坑5106c相同；然而，内部凹坑5106a与中间凹坑5106b和外部凹坑5106c不同，并且中间凹坑5106b与外部凹坑5106c不同。换句话说，每个排5114a，5114b 和5114c中的凹坑5106是不同的。在其他实例中，排中的两个或更多个中的凹坑5106可以是相同的。例如，内部凹坑5106a可与外部凹坑5106c 相同。本文描述的凹坑5106a，5106b和5106c的延伸着陆区5130和5132 可有助于其不同的几何结构。此外，延伸着陆区5130和5132的形状和尺寸由相邻的嵌套凹坑5106的周边5116限制。着陆区5130和5132限定弧形轮廓。在其他实例中，着陆区5030和5032可以是多边形的和/或包括一个或多个线性和/或波状部分。Theinner pocket 5106a is the same, themiddle pocket 5106b is the same, and theouter pocket 5106c is the same; however, theinner pocket 5106a is different from themiddle pocket 5106b and theouter pocket 5106c, and themiddle pocket 5106b is different from theouter pocket 5106c. In other words, thedimples 5106 in eachrow 5114a, 5114b and 5114c are different. In other examples, thedimples 5106 in two or more of the rows may be the same. For example, theinner pocket 5106a can be the same as theouter pocket 5106c. Theextended landing areas 5130 and 5132 of thedimples 5106a, 5106b and 5106c described herein may contribute to their different geometries. In addition, the shape and size of theextended landing zones 5130 and 5132 are limited by theperimeter 5116 of the adjacent nested pockets 5106 .Landing zones 5130 and 5132 define arcuate profiles. In other examples,landing zones 5030 and 5032 may be polygonal and/or include one or more linear and/or wavy portions.

尽管每个排5114a，5114b和5114c中的凹坑是不同的，但是凹坑5106 可被构造成能够将钉形成为相同或基本上相同的成形形状。在其他实例中，凹坑5106可被构造成能够使钉成形为不同形状的钉，诸如不同的高度和/或构造。在某些实例中，凹坑5106可在每个排5114a，5114b和5114c 内纵向变化。例如，在某些实例中，凹坑5106或其部分的深度可沿砧座 5100的长度变化，以适应砧座和钉仓之间的间隙距离沿端部执行器和/ 或组织流的长度的变化，如本文所述。Although the dimples in eachrow 5114a, 5114b, and 5114c are different, thedimples 5106 may be configured to form staples into the same or substantially the same formed shape. In other examples, thepockets 5106 may be configured to enable the staples to be formed into differently shaped staples, such as different heights and/or configurations. In some examples, thedimples 5106 may vary longitudinally within eachrow 5114a, 5114b, and 5114c. For example, in some instances, the depth of thepocket 5106, or a portion thereof, may vary along the length of theanvil 5100 to accommodate the difference in the gap distance between the anvil and the staple cartridge along the length of the end effector and/or tissue flow. changes, as described herein.

示例性中间凹坑5106b在图68-71C中示出。凹坑5106b具有第一端部或近侧端部5110和第二端部或远侧端部5112。凹坑轴线PA(图69) 在凹坑5106b的近侧端部5110和远侧端部5112之间延伸。凹坑5106b包括周边5116，周边5116限定凹坑5106b的边界。周边5116包括线性部分和波状部分。更具体地，周边5116包括线性部分和在其间的波状拐角，线性部分在该拐角处改变方向。再次参见图68，每个凹坑5106的周边 5116的至少一部分紧密地跟踪或平行于一个或多个相邻凹坑5106的周边的至少一部分。凹坑5106b的圆形周边5116可提供更平滑的轮廓，例如，其与具有尖角的凹坑相比可更容易地在钉成形表面5102中压印和/或冲压。Exemplarymiddle dimples 5106b are shown in Figures 68-71C. Thedimple 5106b has a first orproximal end 5110 and a second ordistal end 5112. The dimple axis PA (FIG. 69) extends between theproximal end 5110 and thedistal end 5112 of thedimple 5106b. Thedimple 5106b includes aperimeter 5116 that defines the boundary of thedimple 5106b. Theperimeter 5116 includes a linear portion and a wavy portion. More specifically, theperimeter 5116 includes linear portions and undulating corners therebetween where the linear portions change direction. Referring again to Figure 68, at least a portion of theperimeter 5116 of eachpocket 5106 closely tracks or is parallel to at least a portion of the perimeter of one or moreadjacent pockets 5106. Therounded perimeter 5116 of thedimples 5106b can provide a smoother profile, eg, which can be stamped and/or stamped into thestaple forming surface 5102 more easily than dimples with sharp corners.

凹坑5106b包括近侧杯5120，远侧杯5122，以及在近侧杯5120和远侧杯5122之间延伸的颈部部分5124。当钉被驱动成与钉成形表面5102 成形接触时，近侧杯5120与近侧钉腿对准，并且远侧杯5122与远侧钉腿对准。杯5120和5122被构造成能够将钉腿朝向凹坑轴线PA和凹坑 5106的中心部分(诸如颈部部分5124)引导或传送，并使钉腿变形成所成形的构造。Thepocket 5106b includes aproximal cup 5120, adistal cup 5122, and aneck portion 5124 extending between theproximal cup 5120 and thedistal cup 5122. When the staples are driven into forming contact with thestaple forming surfaces 5102, theproximal cups 5120 are aligned with the proximal staple legs and thedistal cups 5122 are aligned with the distal staple legs. Thecups 5120 and 5122 are configured to guide or transport the staple legs toward the pocket axis PA and the central portion of thepocket 5106, such as theneck portion 5124, and deform the staple legs into the shaped configuration.

主要参见图70，凹坑5106b的每个杯5120,5122限定入口斜坡5140 和出口斜坡5142。当形成钉时，钉腿的尖端可沿入口斜坡5140进入相应的凹坑5120,5122并且沿出口斜坡5142离开相应的凹坑5120,5122。在入口斜坡5140和出口斜坡5142之间的顶点5146处，钉腿的尖端朝向钉基部变形以呈现成形的构造，例如诸如B形或修改的B形。凹坑5106b还在近侧杯5120和远侧杯5122之间的颈部部分5124中限定桥接件5144。桥接件5144与非成形部分5108偏置。更具体地，桥接件5144被定位在非成形部分5108下方或相对于非成形部分5108凹入。Referring primarily to Figure 70, eachcup 5120, 5122 of thepocket 5106b defines aninlet ramp 5140 and anoutlet ramp 5142. When the staples are formed, the tips of the staple legs can enter the correspondingpockets 5120 , 5122 along theinlet ramp 5140 and exit the correspondingpockets 5120 , 5122 along theoutlet ramp 5142 . At the apex 5146 between theinlet ramp 5140 and theoutlet ramp 5142, the tips of the staple legs deform toward the staple base to assume a shaped configuration, such as a B-shape or a modified B-shape, for example. Thepocket 5106b also defines abridge 5144 in theneck portion 5124 between theproximal cup 5120 and thedistal cup 5122.Bridge 5144 is offset fromnon-formed portion 5108 . More specifically, thebridges 5144 are positioned below or recessed relative to thenon-shaped portion 5108 .

主要参见图71A-71C，凹坑5106b包括侧壁5150，侧壁5150从非成形部分5108延伸。侧壁5150包括线性部分和波状部分。侧壁5150朝向每个杯5120,5122的中心区域5121(图69)变宽，并且从每个杯5120,5122 的中心区域5121朝向颈部部分5124变窄。加宽的中心区域5121提供了用于接收钉腿的尖端的扩大的占有面积。当杯5120,5122朝向颈部部分 5124变窄时，杯5120,5122被构造成能够朝向和/或沿凹坑轴线PA传送和/或引导其钉腿和尖端并且进入成形构造。Referring primarily to FIGS. 71A-71C , thedimple 5106b includes asidewall 5150 extending from thenon-formed portion 5108 .Sidewall 5150 includes linear portions and undulating portions. Thesidewall 5150 widens toward the central region 5121 ( FIG. 69 ) of eachcup 5120 , 5122 and narrows from thecentral region 5121 of eachcup 5120 , 5122 toward theneck portion 5124 . The widenedcentral region 5121 provides an enlarged footprint for receiving the tips of the staple legs. As thecups 5120, 5122 narrow toward theneck portion 5124, thecups 5120, 5122 are configured to transmit and/or guide their legs and tips toward and/or along the pocket axis PA and into the shaped configuration.

图71A沿图69中的平面ALL截取，其对应于钉腿的预期着陆位置。例如，可预期钉腿的尖端在平面ALL和凹坑轴线PA的交叉处和/或附近着陆在近侧杯5120中。在平面ALL处，凹坑5106b限定宽度W_A和深度 D_A。图71B中的横截面横跨近侧杯5120和颈部5124之间的过渡截取。图71B示出了限定宽度W_B和深度D_B的凹坑5106b。宽度W_B小于宽度 W_A，并且深度D_B大于深度D_A。换句话说，凹坑5106b从近侧杯5120中的平面ALL朝向颈部5124变窄并加深。平面ALL处的相对大的宽度W_A被构造成能够提供用于接收钉腿的宽盆或容器。图71C中的横截面横跨颈部部分5124截取。图71C示出了限定宽度W_C和深度D_C的凹坑5106b。宽度W_C小于宽度W_B，并且深度D_C小于深度D_B。换句话说，凹坑5106b 继续变窄，并且在横跨桥接件5144的颈部5124中变得更浅。Figure 71A is taken along plane ALL in Figure 69, which corresponds to the intended landing position of the staple legs. For example, the tips of the staple legs may be expected to land in theproximal cup 5120 at and/or near the intersection of the plane ALL and the dimple axis PA. At plane ALL, pit_5106b defines width WA and depth DA_. The cross-section in FIG. 71B is taken across the transition between theproximal cup 5120 and theneck 5124. FIG. 71B shows_a dimple_5106b defining a width WB and a depth DB. Width_WB is less than width_WA and depth_DB is greater than depth DA_. In other words, thedimple 5106b narrows and deepens from the plane ALL in theproximal cup 5120 toward theneck 5124. The relatively large width WA at plane ALL is configured to provide_a wide pot or container for receiving the spike legs. The cross-section in FIG. 71C is taken across theneck portion 5124. Figure_71C shows the pit_5106b defining a width WC and a depth DC. Width_WC is less than width_WB , and depth_DC is less than depth_DB . In other words, thedimples 5106b continue to narrow and become shallower in thenecks 5124 across thebridges 5144.

凹坑5106b的底表面5158是平坦表面。在其他实例中，底表面5158 可具有沿其至少一部分限定的凹槽。在其他实施中，底表面5158可形成槽和/或可包括沿其至少一部分(例如诸如横跨桥接件5144)的隆起或脊。Thebottom surface 5158 of thedimple 5106b is a flat surface. In other examples, thebottom surface 5158 can have grooves defined along at least a portion thereof. In other implementations, thebottom surface 5158 can form grooves and/or can include ridges or ridges along at least a portion thereof (eg, such as across bridges 5144).

现在主要参见图69，凹坑5106b包括近侧延伸着陆区5130和远侧延伸着陆区5132。近侧延伸着陆区5130被定位在近侧杯5120的近侧部分中，并且远侧延伸着陆区5132被定位在远侧杯5122的远侧部分中。更具体地，延伸着陆区5130和5132被定位在钉的预期着陆位置之外。例如，近侧延伸着陆区5130被定位在平面ALL的近侧，并且在钉腿的尖端着陆在平面ALL之外的实例中，近侧延伸着陆区5130可捕获钉腿并将其引导朝向凹坑轴线PA和/或朝向颈部部分5124。Referring now primarily to FIG. 69 , thedimple 5106b includes a proximally extendinglanding zone 5130 and a distally extendinglanding zone 5132 . A proximally extendinglanding zone 5130 is positioned in the proximal portion of theproximal cup 5120 and a distally extendinglanding zone 5132 is positioned in the distal portion of thedistal cup 5122. More specifically, theextended landing zones 5130 and 5132 are positioned outside the intended landing position of the staples. For example, the proximally extendedlanding zone 5130 is positioned proximal of the plane ALL, and in instances where the tips of the staple legs land outside of the plane ALL, the proximally extendedlanding zone 5130 can capture the staple legs and guide them toward the pockets Axis PA and/or towards theneck portion 5124.

延伸着陆区5130和5132的几何结构由相邻钉成形凹坑5106的周边 5016限制。例如，延伸着陆区5130和5132可朝向一个或多个相邻的钉成形凹坑延伸和/或几乎与其邻接接触。延伸着陆区5130和5132和/或凹坑5106b的其他部分可平行于相邻的钉成形凹坑5106延伸。在其他实例中，延伸着陆区5130和5132可邻接一个或多个相邻的钉成形凹坑5106。The geometry ofextension landing zones 5130 and 5132 is bounded by theperimeter 5016 of adjacentstaple forming pockets 5106. For example,extension landing zones 5130 and 5132 may extend toward and/or be in nearly contiguous contact with one or more adjacent staple forming pockets. Theextension landings 5130 and 5132 and/or other portions of thepockets 5106b may extend parallel to adjacentstaple forming pockets 5106. In other examples,extended landing areas 5130 and 5132 may abut one or more adjacentstaple forming pockets 5106 .

再次参见图69，凹坑5106b关于凹坑轴线PA不对称。例如，凹坑 5106b的周边5116关于凹坑轴线PA不对称。此外，凹坑5106b关于穿过颈部部分5124并垂直于凹坑轴线PA的中心轴线CA不对称。例如，凹坑5106b的周边5116关于中心轴线CA不对称，并且近侧杯5120具有与远侧杯5122不同的几何结构。尽管近侧杯5120和远侧杯5122是不同的，但是凹坑5106b可被构造成能够形成对称的钉。例如，再次参见图70，远侧深度D₂可小于近侧深度D₁，以适应砧座和钉仓和/或组织流之间的间隙距离的变化，如本文所述。因此，钉的近侧腿部和远侧腿部的成形高度可相等。在其他实例中，凹坑5106可被构造成能够形成不对称的钉。Referring again to Figure 69, thedimple 5106b is asymmetric about the dimple axis PA. For example, theperimeter 5116 of thedimple 5106b is asymmetric about the dimple axis PA. Furthermore, thedimple 5106b is asymmetrical about a central axis CA that passes through theneck portion 5124 and is perpendicular to the dimple axis PA. For example, theperimeter 5116 of thepocket 5106b is asymmetric about the central axis CA, and theproximal cup 5120 has a different geometry than thedistal cup 5122. Although theproximal cup 5120 and thedistal cup 5122 are different, thepockets 5106b can be configured to form symmetrical staples. For example, referring again to Figure 70, the distal depth D2 may be less_than the proximal depth_D1 to accommodate variations in the gap distance between the anvil and the staple cartridge and/or tissue flow, as described herein. Thus, the formed heights of the proximal and distal legs of the staple may be equal. In other examples, thepockets 5106 may be configured to form asymmetrical staples.

再次参见图69，颈部部分5124比近侧杯5120和远侧杯5122窄。颈部部分5124处的凹坑5106b的变窄的周边5116在近侧杯5120的一部分和远侧杯5122的一部分之间限定接收半岛部5126。接收半岛部5126被定位在凹坑5106b的每个侧面上。接收半岛部5126由凹坑5106b的周边 5116和切线轴线(例如，T_B1或T_B2)界定，该切线轴线与凹坑5106的每个侧面上的近侧杯5120和远侧杯5122的最宽部分相切。第一切线轴线 T_B1被定位在凹坑5106b的第一侧上，并且第二切线轴线T_B2被定位在凹坑5106b的相对侧上。图69中示出的第一切线轴线T_B1和第二切线轴线 T_B2相对于凹坑轴线PA偏斜。在其他实例中，切线轴线T_B1和T_B2中的一个或两个可与凹坑轴线PA平行。Referring again to FIG. 69, theneck portion 5124 is narrower than theproximal cup 5120 and thedistal cup 5122. The narrowedperimeter 5116 of thepocket 5106b at theneck portion 5124 defines a receivingpeninsula 5126 between a portion of theproximal cup 5120 and a portion of thedistal cup 5122. Receivingpeninsulas 5126 are positioned on each side of thepocket 5106b. Receivingpeninsula 5126 is bounded byperimeter 5116 ofpocket 5106b and a tangential axis (eg, T_B1 or T_B2 ) that is the widest ofproximal cup 5120 anddistal cup 5122 on each side ofpocket 5106 Partially tangent. The first tangential axis TB1 is positioned on a first side of the pocket_5106b , and the second tangential axis_TB2 is positioned on the opposite side of thepocket 5106b. The first tangential axis_TB1 and the second tangential axis_TB2 shown in FIG. 69 are skewed with respect to the pit axis PA. In other examples, one or both of the tangential axes T_B1 and T_B2 may be parallel to the dimple axis PA.

再次参见图68，凹坑5106的周边5116沿钉成形表面5102嵌套或互锁。具体地，每个凹坑5106延伸到相邻凹坑5106的接收半岛部5126中。例如，中间凹坑5106b嵌套在内部凹坑5106a和外部凹坑5106c之间。换句话说，中间凹坑5106b延伸到相邻内部凹坑5106a的接收半岛部5126 中并且延伸到相邻外部凹坑5106c的接收半岛部5126中。此外，内部凹坑5106a和外部凹坑5106b与中间凹坑5106b嵌套。更具体地，内部凹坑 5106a延伸到相邻中间凹坑5106b的接收半岛部5126中，并且外部凹坑 5106c延伸到相邻中间凹坑5106b的接收半岛部5126中。在各种实例中，中间凹坑5106b的远侧延伸着陆区5132被定位在内部凹坑5106a的接收半岛部5126中，中间凹坑5106b的近侧延伸着陆区5130被定位在外部凹坑5106c的接收半岛部5126中，内部凹坑5106a的远侧延伸着陆区5132 被定位在中间凹坑5106b的接收半岛部5126中，并且外部凹坑5106c的近侧延伸着陆区5130被定位在中间凹坑5106b的接收半岛部5126中。Referring again to FIG. 68, theperimeters 5116 of thepockets 5106 nest or interlock along thestaple forming surface 5102. Specifically, eachpocket 5106 extends into the receivingpeninsula 5126 of anadjacent pocket 5106 . For example,middle pocket 5106b is nested betweeninner pocket 5106a andouter pocket 5106c. In other words, themiddle pocket 5106b extends into the receivingpeninsula 5126 of the adjacentinner pocket 5106a and into the receivingpeninsula 5126 of the adjacentouter pocket 5106c. In addition,inner dimple 5106a andouter dimple 5106b are nested withmiddle dimple 5106b. More specifically, theinner pocket 5106a extends into the receivingpeninsula 5126 of the adjacentintermediate pocket 5106b, and theouter pocket 5106c extends into the receivingpeninsula 5126 of the adjacentintermediate pocket 5106b. In various examples, the distally extendinglanding zone 5132 of themiddle pocket 5106b is positioned in the receivingpeninsula 5126 of theinner pocket 5106a and the proximally extendinglanding zone 5130 of themiddle pocket 5106b is positioned in theouter pocket 5106c In the receivingpeninsula 5126, thedistally extending land 5132 of theinner pocket 5106a is positioned in the receivingpeninsula 5126 of themiddle pocket 5106b, and theproximally extending land 5130 of theouter pocket 5106c is positioned within themiddle pocket 5106b The receivingpeninsula section 5126.

凹坑5106的几何结构便于凹坑5106在钉成形表面5102中的嵌套。例如，因为凹坑5106包括在两个扩大的杯5120和5122之间的变窄的颈部部分5124，所以另一个凹坑5106的扩大的杯5120,5122中的一个可定位成邻近变窄的颈部部分5124。例如，扩大的杯5120,5122中的一个可与相邻的凹坑5106的一部分对准和/或被其接收。在所述实例中，可优化由凹坑5106覆盖的钉成形表面5102的表面区域。例如，由凹坑5106 覆盖的钉成形表面5102的表面区域被最大化。钉成形表面5102的“成形比”是非成形部分5108与成形部分(即，凹坑5106)的比率。在至少一个实例中，例如，成形比可以是至少1:1。在某些实例中，钉成形表面5102的60％以上或75％以上可被钉成形凹坑5106覆盖。The geometry of thedimples 5106 facilitates the nesting of thedimples 5106 in thestaple forming surface 5102. For example, becausedimple 5106 includes a narrowedneck portion 5124 between twoenlarged cups 5120 and 5122, one of theenlarged cups 5120, 5122 of anotherdimple 5106 may be positioned adjacent to the narrowedNeck section 5124. For example, one of theenlarged cups 5120 , 5122 may be aligned with and/or received by a portion of anadjacent pocket 5106 . In the example, the surface area of thestaple forming surface 5102 covered by thedimples 5106 can be optimized. For example, the surface area of thestaple forming surface 5102 covered by thedimples 5106 is maximized. The "forming ratio" of thestaple forming surface 5102 is the ratio of theunformed portion 5108 to the formed portion (ie, the dimples 5106). In at least one example, for example, the forming ratio can be at least 1:1. In some examples, more than 60% or more than 75% of thestaple forming surface 5102 may be covered by thestaple forming pockets 5106 .

现在参见图72-76C，示出了砧座5200的一部分中的钉成形凹坑5206。类似于砧座3800，凹坑5206沿砧座5200的钉成形表面5202布置成人字形布置。砧座5200包括钉成形表面5202和纵向狭槽5204。纵向狭槽5204 沿砧座5200的纵向轴线LA延伸。在某些实例中，击发元件和/或切割元件可在击发行程的至少一部分期间平移穿过纵向狭槽5204。钉成形凹坑 5206限定在钉成形表面5202中。钉成形表面5202还包括围绕凹坑5206 延伸的非成形部分5208。非成形部分5208完全围绕每个凹坑5206延伸。换句话说，非成形部分5208围绕钉成形凹坑5206。在其他实例中，两个或更多个相邻凹坑5206的至少一部分可邻接接触，使得非成形部分5208 不被定位在两者间。Referring now to Figures 72-76C,staple forming pockets 5206 in a portion ofanvil 5200 are shown. Similar to theanvil 3800, thepockets 5206 are arranged in a herringbone arrangement along thestaple forming surface 5202 of theanvil 5200.Anvil 5200 includesstaple forming surface 5202 andlongitudinal slot 5204. Thelongitudinal slot 5204 extends along the longitudinal axis LA of theanvil 5200. In certain examples, the firing element and/or cutting element can translate throughlongitudinal slot 5204 during at least a portion of the firing stroke.Staple forming pockets 5206 are defined in thestaple forming surface 5202. Thestaple forming surface 5202 also includes anon-forming portion 5208 extending around thepocket 5206. Anon-shaped portion 5208 extends completely around eachpocket 5206. In other words, thenon-formed portion 5208 forms thepocket 5206 around the staple. In other examples, at least a portion of two or moreadjacent pockets 5206 may be in abutting contact such that thenon-shaped portion 5208 is not positioned therebetween.

可优化钉成形表面5202的成形比。通过优化成形比，更多的钉可成形和/或成形为他们期望的构造。在某些实例中，砧座5200的非成形部分5208的表面区域可相对于钉成形凹坑5206被最小化。除此之外或另选地，钉成形凹坑5206的占有面积可延伸或扩大，以最大化钉成形表面 5202的被设计用于捕获和形成钉的部分。The forming ratio of thestaple forming surface 5202 can be optimized. By optimizing the forming ratio, more staples can be formed and/or formed into their desired configuration. In certain examples, the surface area of thenon-forming portion 5208 of theanvil 5200 can be minimized relative to thestaple forming pockets 5206. Additionally or alternatively, the footprint of thestaple forming pockets 5206 may be extended or enlarged to maximize the portion of thestaple forming surface 5202 designed to capture and form staples.

图72中示出的凹坑5206在纵向狭槽5204的第一侧上被布置成内排 5214a、中间排5214b和外排5214c。内部凹坑5206a被定位在内排5214a 中，中间凹坑5206b被定位在中间排5214b中，并且外部凹坑5206c被定位在外排5214c中。尽管未在图72中示出，在至少一个实例中，狭槽5204 的相对侧上的凹坑5206可形成纵向狭槽5204的第一侧上的凹坑5206的镜像反射。在其他实例中，钉成形表面5202中的凹坑5206的布置可相对于狭槽5204不对称，并且在某些实例中，砧座5200可不包括纵向狭槽5204。在各种实例中，凹坑5206可在狭槽5204的每个侧面上被布置成少于或多于三排。Thedimples 5206 shown in Figure 72 are arranged on the first side of thelongitudinal slot 5204 in aninner row 5214a, amiddle row 5214b, and anouter row 5214c. Theinner pockets 5206a are positioned in theinner row 5214a, themiddle pockets 5206b are positioned in themiddle row 5214b, and theouter pockets 5206c are positioned in theouter row 5214c. Although not shown in FIG. 72 , in at least one example, thedimples 5206 on opposite sides of theslot 5204 may form mirror reflections of thedimples 5206 on the first side of thelongitudinal slot 5204 . In other examples, the arrangement of thepockets 5206 in thestaple forming surface 5202 may be asymmetric relative to theslots 5204, and in some examples, theanvil 5200 may not include thelongitudinal slots 5204. In various examples, thedimples 5206 may be arranged in fewer or more than three rows on each side of theslot 5204.

图72中示出的凹坑5206是相同的。限定在钉成形表面5202中的每个凹坑5206具有相同的几何结构。在其他实例中，凹坑5206的几何结构可沿砧座5200的长度逐排和/或纵向地变化。例如，在某些实例中，凹坑5206的深度可沿砧座5200的长度变化，以适应砧座和钉仓之间的间隙距离沿端部执行器和/或组织流的长度的变化，如本文所述。Thedimples 5206 shown in Figure 72 are the same. Eachpocket 5206 defined in thestaple forming surface 5202 has the same geometry. In other examples, the geometry of thepockets 5206 may vary row by row and/or longitudinally along the length of theanvil 5200 . For example, in certain instances, the depth of thepockets 5206 can vary along the length of theanvil 5200 to accommodate variations in the gap distance between the anvil and the staple cartridge along the length of the end effector and/or tissue flow, such as described in this article.

凹坑5206可被构造成能够将钉形成为相同或基本上相同的成形形状。如本文所述，凹坑5206可被构造成能够将每个钉形成为相同的不对称形状。在其他实例中，凹坑5206可被构造成能够使钉成形为不同形状的钉，诸如不同的高度和/或构造。Thepockets 5206 can be configured to form the staples into the same or substantially the same shaped shape. As described herein, thedimples 5206 can be configured to form each peg into the same asymmetrical shape. In other examples, thepockets 5206 may be configured to enable the staples to be formed into differently shaped staples, such as different heights and/or configurations.

示例性中间凹坑5206b在图73-76C中示出。凹坑5206b具有第一端部或近侧端部5210和第二端部或远侧端部5212。凹坑轴线PA(图72) 在凹坑5206b的近侧端部5210和远侧端部5212之间延伸。凹坑5206b包括周边5216，周边5216限定凹坑5206b的边界。周边5216包括线性部分和波状部分。An exemplaryintermediate dimple 5206b is shown in Figures 73-76C. Thedimple 5206b has a first orproximal end 5210 and a second ordistal end 5212. The dimple axis PA (FIG. 72) extends between theproximal end 5210 and thedistal end 5212 of thedimple 5206b. Thedimple 5206b includes a perimeter 5216 that defines the boundary of thedimple 5206b. The perimeter 5216 includes a linear portion and a wavy portion.

凹坑5206b还包括近侧杯5220，远侧杯5222，以及在近侧杯5220和远侧杯5222之间延伸的颈部部分5224。当钉被驱动成与钉成形表面5202 成形接触时，近侧杯5220与近侧钉腿对准，并且远侧杯5222与远侧钉腿对准。杯5220和5222被构造成能够将钉腿朝向凹坑轴线PA和凹坑 5206的中心部分(诸如颈部部分5224)引导或传送，并使钉腿变形成所成形的构造。在其他实例中，杯5222可在杯5220的近侧。Thepocket 5206b also includes aproximal cup 5220, adistal cup 5222, and aneck portion 5224 extending between theproximal cup 5220 and thedistal cup 5222. When the staples are driven into forming contact with thestaple forming surfaces 5202, theproximal cups 5220 are aligned with the proximal staple legs and thedistal cups 5222 are aligned with the distal staple legs.Cups 5220 and 5222 are configured to guide or transport the staple legs toward pocket axis PA and a central portion ofpocket 5206, such asneck portion 5224, and deform the staple legs into a shaped configuration. In other examples,cup 5222 can be proximal ofcup 5220.

主要参见图70，凹坑5206b的每个杯5220和5222分别限定入口斜坡5240a和5240b以及出口斜坡5242a和5242b。当形成钉时，钉腿的尖端可沿入口斜坡5240a，5240b进入相应的凹坑5220,5222并且沿出口斜坡5242a，5242b离开相应的凹坑5220,5222。在分别在入口斜坡5240a， 5240b和出口斜坡5242a，5242b之间的顶点5246a，5246b处，钉腿的尖端朝向钉基部变形以呈现成形的构造，例如诸如B形或修改的B形。凹坑5206b还在近侧杯5220和远侧杯5222之间限定桥接件5244。桥接件 5244与非成形部分5208偏置。更具体地，桥接件5244被定位在非成形部分5208下方或相对于非成形部分5208凹入。Referring primarily to Figure 70, eachcup 5220 and 5222 ofpocket 5206b definesinlet ramps 5240a and 5240b andoutlet ramps 5242a and 5242b, respectively. As the staples are formed, the tips of the staple legs can enter therespective pockets 5220, 5222 along the entry ramps 5240a, 5240b and exit therespective pockets 5220, 5222 along theexit ramps 5242a, 5242b. Atvertices 5246a, 5246b betweeninlet ramps 5240a, 5240b andoutlet ramps 5242a, 5242b, respectively, the tips of the staple legs deform toward the staple base to assume a shaped configuration, such as a B-shape or a modified B-shape, for example. Thedimple 5206b also defines abridge 5244 between theproximal cup 5220 and thedistal cup 5222.Bridge 5244 is offset fromnon-formed portion 5208. More specifically, thebridges 5244 are positioned below or recessed relative to thenon-shaped portion 5208 .

再次参见图73，凹坑5206b关于凹坑轴线PA对称。例如，凹坑5206b 的周边5216关于凹坑轴线PA对称。此外，凹坑5206b关于穿过颈部部分5224并垂直于凹坑轴线PA的中心轴线CA不对称。例如，凹坑5206b 的周边5216关于中心轴线CA不对称，并且近侧杯5220具有与远侧杯 5222不同的几何结构。杯5220和5222的不对称性被构造成能够形成不对称的钉。例如，再次参见图74，远侧深度D₂小于近侧深度D₁，近侧深度D₁被构造成能够形成在近侧腿部处具有比在远侧腿部处更大的成形高度的钉。远侧深度D₂可比近侧深度D₁小约0.002英寸。在其他实例中，远侧深度D₂和近侧深度D₁之间的差值可大于和/或小于0.002英寸。在某些实例中，差值可以是钉直径的1％至10％。例如，差值可以是钉直径的约2％。在其他实例中，钉的成形高度在远侧腿部处可比在近侧腿部处更大。每个杯5220,5222的长度也不同。例如，远侧长度D₂大于图74 中的近侧长度D₁。另外，凹坑5206b中的入口斜坡5240a和5240b的倾斜是不同的，并且凹坑5206b中的出口斜坡5242a和5242b的倾斜也是不同的。Referring again to Figure 73, thedimple 5206b is symmetrical about the dimple axis PA. For example, the perimeter 5216 of thedimple 5206b is symmetrical about the dimple axis PA. Additionally, thedimple 5206b is asymmetric about a central axis CA that passes through theneck portion 5224 and is perpendicular to the dimple axis PA. For example, the perimeter 5216 of thepocket 5206b is asymmetric about the central axis CA, and theproximal cup 5220 has a different geometry than thedistal cup 5222. The asymmetry ofcups 5220 and 5222 is configured to enable the formation of asymmetric staples. For example, referring again to Figure 74, the distal depth D2 is less_than the proximal depth D1, which is configured to enable the formation_of staples having_a greater formed height at the proximal leg than at the distal leg . The distal depth D2 may be_about 0.002 inches less_than the proximal depth D1._In other examples, the difference between distal depth D2 and proximal depth D1 may be greater and/or less_than 0.002 inches. In some instances, the difference may be 1% to 10% of the nail diameter. For example, the difference may be about 2% of the nail diameter. In other examples, the formed height of the staples may be greater at the distal leg than at the proximal leg. The length of eachcup 5220, 5222 is also different. For example, the distal length D₂ is greater than the proximal length D₁ in FIG. 74 . In addition, the inclination of theinlet ramps 5240a and 5240b in thepocket 5206b is different, and the inclination of the outlet ramps 5242a and 5242b in thepocket 5206b is also different.

在各种实例中，凹坑5206b的一部分中的减小的深度可改善砧座的刚度。例如，因为远侧深度D₂小于近侧深度D₁，所以砧座5200由更多材料构成，这可增加其刚度。此外，因为增加的材料位于砧座5200的远侧部分中，所以这种部分可具有增加的刚度，这可限制砧座朝向远侧端部的翘曲或变形。In various examples, the reduced depth in a portion of thepocket 5206b can improve the stiffness of the anvil. For example, because the distal depth D2 is less_than the proximal depth D1, theanvil 5200 is constructed_of more material, which may increase its stiffness. Additionally, because the increased material is located in the distal portion of theanvil 5200, such portion may have increased stiffness, which may limit buckling or deformation of the anvil toward the distal end.

近侧杯5220和远侧杯5222的几何结构的差异可适应组织运动或流动。更具体地，当组织抵靠砧座5200被夹紧时，被夹紧的组织中的流体可朝向相邻的未夹紧组织流动或运动。组织可朝向砧座5200的纵向侧面侧向流动，朝向砧座5200的远侧端部朝远侧流动，和/或朝向砧座5200 的近侧端部朝近侧流动。在某些实例中，当切割边缘被朝远侧推进穿过组织时，组织可相对于砧座5200流动。在所述实例中，组织可侧向地、朝远侧和/或朝近侧流动，但由于切割边缘的远侧运动，所以组织主要朝远侧流动。在切割边缘朝近侧运动以切开组织的实例中，组织的运动或流动在切割行程期间通常是朝近侧的。近侧杯5220和远侧杯5222的不同几何结构分别可适应组织的流动，这可使嵌入其中的钉腿移位或偏斜。The differences in the geometry of theproximal cup 5220 and thedistal cup 5222 can accommodate tissue movement or flow. More specifically, when tissue is clamped againstanvil 5200, fluid in the clamped tissue may flow or move toward adjacent unclamped tissue. Tissue may flow laterally toward the longitudinal sides of theanvil 5200 , distally toward the distal end of theanvil 5200 , and/or proximally toward the proximal end of theanvil 5200 . In certain instances, tissue can flow relative toanvil 5200 as the cutting edge is advanced distally through the tissue. In the example, the tissue may flow laterally, distally, and/or proximally, but the tissue flows primarily distally due to the distal movement of the cutting edge. In instances where the cutting edge is moved proximally to cut tissue, the movement or flow of the tissue is generally proximal during the cutting stroke. The different geometries of theproximal cup 5220 and thedistal cup 5222, respectively, can accommodate the flow of tissue, which can displace or deflect the staple legs embedded therein.

主要参见图75A-76C，凹坑5206b包括侧壁5250，侧壁5250从非成形部分5208延伸。杯5220,5222被构造成能够朝向和/或沿凹坑轴线PA 传送和/或引导其钉腿和尖端并且进入成形构造。由于近侧杯5220和远侧杯5222的不同几何结构，在被驱动成与凹坑5206b成形接触时，近侧钉腿的路径可与远侧钉腿的路径不同。在某些实例中，不对称的钉凹坑5206b可由对称的未成形钉形成不对称的钉。除此之外或另选地，不对称的未成形钉可通过钉凹坑5206b形成为不对称的成形钉。Referring primarily to FIGS. 75A-76C , thedimple 5206b includes asidewall 5250 extending from thenon-formed portion 5208. Thecups 5220, 5222 are configured to convey and/or guide their legs and tips toward and/or along the pocket axis PA and into the shaped configuration. Due to the different geometries of theproximal cup 5220 and thedistal cup 5222, the path of the proximal staple legs may be different from the path of the distal staple legs when driven into forming contact with thedimples 5206b. In certain examples, theasymmetrical staple pockets 5206b may be formed from symmetrical unformed staples to form asymmetrical staples. Additionally or alternatively, asymmetrical unformed staples may be formed into asymmetrical formed staples bystaple pockets 5206b.

图75A沿图73中的平面ALL₁截取，其对应于近侧钉腿的预期着陆位置。例如，可预期近侧钉腿的尖端在平面ALL₁和凹坑轴线PA的交叉处和/或附近着陆在近侧杯5220中。在平面ALL₁处，近侧杯5220限定宽度W1_A和深度D1_A。图75B中的横截面横跨近侧杯5220和颈部5224之间的过渡截取。图75B示出了近侧杯5220，其限定宽度W1_B和深度D1_B。宽度W1_B大于宽度W1_A，并且深度D1_B大于深度D1_A。换句话说，近侧杯5220从近侧杯5220中的平面ALL₁朝向颈部5224变宽和加深。图75C 中的横截面横跨颈部部分5224的近侧端部截取。图75C示出了限定宽度 W1_C和深度D1_C的凹坑5206b。宽度W1_C小于宽度W1_B，并且深度D1_C小于深度D1_B。换句话说，凹坑5206b继续变窄，并且在横跨桥接件5244 的颈部5224中变得更浅。Figure 75A is taken along plane ALL₁ in Figure 73, which corresponds to the intended landing position of the proximal staple legs. For example, the tips of the proximal staple legs may be expected to land in theproximal cup 5220 at and/or near the intersection of the plane ALL₁ and the dimple axis PA. At plane ALL₁ ,proximal cup 5220 defines width W1_A and depth D1_A . The cross-section in FIG. 75B is taken across the transition between theproximal cup 5220 and theneck 5224. Figure 75B shows theproximal cup 5220, which defines a width W1_B and a depth D1_B . Width W1_B is greater than width W1_A , and depth D1_B is greater than depth D1_A . In other words, theproximal cup 5220 widens and deepens from the plane ALL₁ in theproximal cup 5220 toward theneck 5224. The cross-section in FIG. 75C is taken across the proximal end of theneck portion 5224. Figure 75C shows the pit_5206b defining a width W1C and a depth_D1C . Width W1_C is less than width W1_B , and depth D1_C is less than depth D1_B . In other words, thedimple 5206b continues to narrow and become shallower in theneck 5224 across thebridge 5244.

图76A沿图73中的平面ALL₂截取，其对应于远侧钉腿的预期着陆位置。例如，可预期远侧钉腿的尖端在平面ALL₂和凹坑轴线PA的交叉处和/或附近着陆在远侧杯5222中。在平面ALL₂处，远侧杯5222限定宽度W2_A和深度D2_A。宽度W2_A与宽度W1_A不同，并且深度D2_A与深度 D1_A不同。图76B中的横截面横跨远侧杯5222和颈部5224之间的过渡截取。图76B示出了限定宽度W2_B和深度D2_B的远侧杯5222。宽度W2_B与宽度W1_B不同，并且深度D2_B与深度D1_B不同。宽度W2_B小于宽度W2_A，并且深度D2_B大于深度D2_A。换句话说，远侧杯5222从远侧杯5222中的平面ALL₂朝向颈部5224变窄和加深。图76C中的横截面横跨颈部部分 5224的远侧端部截取。图76C示出了限定宽度W2_C和深度D2_C的凹坑 5206b。宽度W2_C与宽度W1_C不同，并且深度D2_C与深度D1_C不同。宽度 W2_C小于宽度W2_B，并且深度D2_C小于深度D2_B。换句话说，凹坑5206b 继续变窄，并且在横跨桥接件5244的颈部5224中变得更浅。Figure 76A is taken along plane ALL₂ in Figure 73, which corresponds to the intended landing position of the distal staple legs. For example, the tips of the distal staple legs may be expected to land in thedistal cup 5222 at and/or near the intersection of the plane ALL₂ and the dimple axis PA. At plane ALL₂ , thedistal cup 5222 defines a width W2A and_a depth_D2A . Width W2_A is different from width W1_A , and depth D2_A is different from depth D1_A. The cross-section in FIG. 76B is taken across the transition between thedistal cup 5222 and theneck 5224. Figure_76B shows thedistal cup 5222 defining a width_W2B and a depth D2B. Width W2_B is different from width W1_B , and depth D2_B is different from depth D1_B. The width W2_B is smaller than the width W2_A , and the depth D2_B is greater than the depth D2_A . In other words, thedistal cup 5222 narrows and deepens from the plane ALL₂ in thedistal cup 5222 toward theneck 5224. The cross-section in FIG. 76C is taken across the distal end of theneck portion 5224. FIG._76C shows a dimple_5206b defining a width W2C and a depth D2C. Width W2C is different from width_W1C , and depth_D2C is different from depth_D1C_. Width W2_C is less than width W2_B , and depth D2_C is less than depth D2_B . In other words, thedimples 5206b continue to narrow and become shallower in thenecks 5224 across thebridges 5244.

凹坑5206b的底表面5258是平坦表面。在其他实例中，底表面5258 可具有沿其至少一部分限定的凹槽。在其他实施中，底表面5258可形成槽和/或可包括沿其至少一部分(例如诸如横跨桥接件5244)的隆起或脊。Thebottom surface 5258 of thedimple 5206b is a flat surface. In other examples, thebottom surface 5258 can have grooves defined along at least a portion thereof. In other implementations, thebottom surface 5258 can form grooves and/or can include ridges or ridges along at least a portion thereof (eg, such as across bridges 5244).

现在主要参见图73，凹坑5206b包括近侧延伸着陆区5230和远侧延伸着陆区5232。近侧延伸着陆区5230被定位在近侧杯5220的近侧部分中，并且远侧延伸着陆区5232被定位在远侧杯5222的远侧部分中。更具体地，延伸着陆区5230和5232被定位在钉的预期着陆位置之外。例如，近侧延伸着陆区5230被定位在平面ALL₁的近侧，并且在钉腿的尖端着陆在平面ALL₁之外的实例中，近侧延伸着陆区5230可捕获钉腿并将其引导朝向凹坑轴线PA和/或朝向颈部部分5224。远侧延伸着陆区 5232被定位在平面ALL₂的远侧，并且在钉腿的尖端落在平面ALL₂之外的实例中，远侧延伸着陆区5232可捕获钉腿并将其引导朝向凹坑轴线 PA和/或朝向颈部部分5224。在某些实例中，延伸着陆区5230,5232的几何结构可由相邻的嵌套的钉成形凹坑5206的几何结构约束或限制。Referring now primarily to FIG. 73 , thedimple 5206b includes a proximally extendinglanding zone 5230 and a distally extendinglanding zone 5232 . A proximally extendinglanding zone 5230 is positioned in the proximal portion of theproximal cup 5220, and a distally extendinglanding zone 5232 is positioned in the distal portion of thedistal cup 5222. More specifically,extended landing zones 5230 and 5232 are positioned outside of the staple's intended landing location. For example, the proximally extendedlanding zone 5230 is positioned proximal of plane ALL₁ , and in instances where the tips of the staple legs land outside of plane ALL₁ , the proximally extendedlanding zone 5230 can capture the staple legs and guide them toward The dimple axis PA and/or towards theneck portion 5224. The distallyextended landing zone 5232 is positioned distal of plane ALL₂ , and in instances where the tip of the staple leg falls outside of plane ALL₂ , the distally extendedlanding zone 5232 can capture the staple leg and guide it towards the pocket Axis PA and/or towards theneck portion 5224. In certain examples, the geometry of theextended landing zones 5230 , 5232 may be constrained or limited by the geometry of adjacent nestedstaple forming pockets 5206 .

再次参见图73，颈部部分5224比近侧杯5220和远侧杯5222窄。颈部部分5224处的凹坑5206b的变窄的周边5216在近侧杯5220的一部分和远侧杯5222的一部分之间限定接收半岛部5226。接收半岛部5226被定位在凹坑5206b的每个侧面上。接收半岛部5226由凹坑5206b的周边 5216和切线轴线(例如，T_B1和T_B2)界定，该切线轴线与凹坑5206的每个侧面上的近侧杯5220和远侧杯5222的最宽部分相切。第一切线轴线 T_B1被定位在凹坑5206b的第一侧上，并且第二切线轴线T_B2被定位在凹坑5206b的相对侧上。图73中示出的第一切线轴线T_B1和第二切线轴线 T_B2相对于凹坑轴线PA偏斜。在其他实例中，切线轴线T_B1和T_B2中的一个或两个可与凹坑轴线PA平行。Referring again to FIG. 73, theneck portion 5224 is narrower than theproximal cup 5220 and thedistal cup 5222. The narrowed perimeter 5216 of thepocket 5206b at theneck portion 5224 defines a receivingpeninsula 5226 between a portion of theproximal cup 5220 and a portion of thedistal cup 5222. Receivingpeninsulas 5226 are positioned on each side of thepocket 5206b. Receivingpeninsula 5226 is bounded by perimeter 5216 ofpocket 5206b and a tangential axis (eg, T_B1 and T_B2 ) that is the widest of proximal anddistal cups 5220 and 5222 on each side ofpocket 5206 Partially tangent. The first tangential axis TB1 is positioned on a first side of the pocket_5206b , and the second tangential axis_TB2 is positioned on the opposite side of thepocket 5206b. The first and second tangential axes_TB1 and_TB2 shown in FIG. 73 are skewed with respect to the pit axis PA. In other examples, one or both of the tangential axes T_B1 and T_B2 may be parallel to the dimple axis PA.

在各种实例中，凹坑5206的几何结构可有助于凹坑5206在钉成形表面5202中的嵌套和/或闭合布置。例如，可优化由凹坑5206覆盖的钉成形表面5202的表面区域。钉成形表面5202的“成形比”是非成形部分5208与成形部分(即，凹坑5206)的比率。在至少一个实例中，例如，成形比可以是至少1:1。In various examples, the geometry of thedimples 5206 may facilitate a nested and/or closed arrangement of thedimples 5206 in thestaple forming surface 5202. For example, the surface area of thestaple forming surface 5202 covered by thedimples 5206 can be optimized. The "forming ratio" of thestaple forming surface 5202 is the ratio of theunformed portion 5208 to the formed portion (ie, the dimples 5206). In at least one example, for example, the forming ratio can be at least 1:1.

如本文所述，用于端部执行器的钉仓中的钉腔和钉的布置可对应于或匹配端部执行器的砧座中的钉成形凹坑的布置。更具体地，每个钉腔的角度取向和间距可匹配相应的钉成形凹坑的角度取向和间距。例如，当钉腔以人字形图案布置时，钉成形凹坑可以对应的人字形图案布置。As described herein, the arrangement of the staple cavities and staples in the staple cartridge for the end effector may correspond to or match the arrangement of the staple forming pockets in the anvil of the end effector. More specifically, the angular orientation and spacing of each staple cavity may match the angular orientation and spacing of the corresponding staple forming pockets. For example, when the staple cavities are arranged in a herringbone pattern, the staple forming pockets may be arranged in a corresponding herringbone pattern.

在某些实例中，端部执行器可包括具有钉腔布置的钉仓和具有钉成形凹坑的非对应布置的砧座。例如，钉腔可相对于纵向轴线倾斜地取向，并且钉成形凹坑可平行于纵向轴线进行取向。在某些实例中，例如，端部执行器可被构造成能够接收具有不同的钉腔布置的不同钉仓，并且端部执行器的砧座可与所有不同的钉仓和其中的钉腔的排列不相容。在所述实例中，砧座可改装或适配成具有附件诸如砧座板，其具有合适的钉成形凹坑的布置。In certain examples, the end effector may include a staple cartridge having a staple cavity arrangement and an anvil having a non-corresponding arrangement of staple forming pockets. For example, the staple cavities can be oriented obliquely with respect to the longitudinal axis, and the staple forming pockets can be oriented parallel to the longitudinal axis. In some instances, for example, the end effector may be configured to receive different staple cartridges with different staple cavity arrangements, and the anvil of the end effector may be different from all the different staple cartridges and staple cavities therein. The permutations are incompatible. In the described example, the anvil may be retrofitted or adapted to have an accessory such as an anvil plate with a suitable arrangement of staple forming pockets.

外科端部执行器5500在图77-79中示出。类似于端部执行器1100(图 1-4)，端部执行器5500包括细长通道1102，细长通道1102被构造成能够将钉仓5510可操作地支撑在其中。钉仓5510在许多方面类似于钉仓 1110。例如，钉仓包括具有平台5515的钉仓体5511。纵向狭槽5514从主体5511的近侧端部部分5512朝向主体5511的远侧端部部分5513延伸穿过平台5515。成角度取向的钉腔5516限定在仓体5511中，并且每个钉腔5516在平台5515中限定开口。每个钉腔5516的开口相对于纵向狭槽 5514以倾斜角取向。钉腔5516以人字形图案布置。钉可移除地被定位在钉腔中。Asurgical end effector 5500 is shown in Figures 77-79. Similar to end effector 1100 (FIGS. 1-4),end effector 5500 includes anelongated channel 1102 configured to operably support astaple cartridge 5510 therein. Thestaple cartridge 5510 is similar to thestaple cartridge 1110 in many respects. For example, the staple cartridge includes astaple cartridge body 5511 having aplatform 5515.Longitudinal slot 5514 extends throughplatform 5515 fromproximal end portion 5512 ofbody 5511 towarddistal end portion 5513 ofbody 5511 . Angularly orientedstaple cavities 5516 are defined in thecartridge body 5511 and eachstaple cavity 5516 defines an opening in theplatform 5515. The opening of eachstaple cavity 5516 is oriented at an oblique angle relative to thelongitudinal slot 5514. Thestaple cavities 5516 are arranged in a herringbone pattern. The staples are removably positioned in the staple cavities.

端部执行器5500还包括砧座5530，砧座5530相对于细长通道1102 被可枢转地支撑。砧座5530在许多方面类似于砧座1130。例如，砧座 5530包括钉成形表面5502和纵向狭槽5504。在某些实例中，例如，击发元件和/或切割元件诸如滑动组件1120和/或击发构件1760(图4)在击发行程的至少一部分期间可平移通过纵向狭槽5504。组织止挡件5531朝向钉仓5510向下延伸，以控制组织在仓体5511的近侧端部部分5512和砧座5530之间的定位。钉成形凹坑5506限定在钉成形表面5502中，其还包括围绕凹坑5506延伸的非成形部分5508。钉成形凹坑5506平行于纵向狭槽5504取向。换句话说，钉成形凹坑5506的布置与钉腔5516的布置不匹配或不对应。如果钉从钉仓5510击发成与砧座5530成形接触，则大多数这种钉可能未成形和/或畸形。Theend effector 5500 also includes ananvil 5530 that is pivotally supported relative to theelongated channel 1102 .Anvil 5530 is similar toanvil 1130 in many respects. For example, theanvil 5530 includes astaple forming surface 5502 and alongitudinal slot 5504.
